3x^2+7x+2 how to factor​

Your smallest angle is 26°

Angles in a triangle add up to 180°. This means:

Angle1 + Angle2 + Angle3 = 180°

The second angle of a triangle is 3 times as large as the first.

Angle2 = 3 * Angle1

The third angle is 50° more than the first.

Angle3 = Angle1 + 50°

Substitute these into the first formula, in terms of Angle1.

Angle1 + (3 * Angle1) + (Angle1 + 50°) = 180°

Expand and simplify.

5 * Angle1 + 50° = 180°

Put it into the formula Ax = B. You will have all the variables on one side and the integers on the other.

5 * Angle1 + 50° = 180°

5 * Angle1 + 50° - 50° = 180° - 50°

5 * Angle1 = 130°

Put it into the formula x = b. Solve to find 1 of the variable.

5 * Angle1 = 130°

5 * Angle1 / 5 = 130° / 5

Angle1 = 26°

Check this is right by substituting into the given formulas.

Angle2 = 3 * Angle1

Angle2 = 3 * 26

78 = 3 * 26

Angle3 = Angle1 + 50°

Angle3 = 26 + 50°

76 = 26 + 50°

Angle1 + Angle2 + Angle3 = 180°

26 + 78 + 76 = 180°

The smallest angle of the triangle is 26 degrees.

The question is referring to a triangle, and the sum of the angles in a triangle is always 180°. Let's denote the first angle as 'x'. According to the question, the second angle is 3x and the third angle is x + 50°. Therefore, we set up the equation x + 3x + x + 50 = 180. This simplifies to 5x + 50 = 180. After subtracting 50 on both sides of the equation, we get 5x = 130, and hence, x = 130 / 5 = 26. Therefore, the smallest angle is 26°.

We need to first find the perimeter, so 2(20+38) = 116 feet

Next we multiply 116 by 22 to get $2552

Answer:

Cost to fence the rectangular pool = $2552

Step-by-step explanation:

To find the cost to fence the rectangular pool, we need to find the perimeter of the rectangular pool.

Given: length = 38 feet and wide = 20 feet

Perimeter of a rectangle = 2(length + width)

Now plug in the given values in the above formula, we get

Perimeter of the rectangle pool = 2 (38 + 20)

= 2(58)

= 116 feet

A fencing company charges $22 per foot to install a wood fence.

To fence 116 feet, we need to multiply $22 and 116.

Cost to fence the rectangular pool = $22*116 = $2552.

Answer: The correct answer is the one on the lower left.

Step-by-step explanation: You are looking for the equation that is five times the quotient of a number and 10.

Since it is five times the quotient, you are looking for an expression that has 5 outside of the parentheses, and a quotient means that there is division taking place. The only option that has 5 outside parentheses with division inside the parentheses is the lower left.

Answer: The answer is lower left: C. 5(z/10).

Step-by-step explanation:

The division of 5,945 by 612 yields a quotient of 9 with a remainder of 437, which corresponds to option C: 9 R437.

To solve the division problem 5,945 \/ 612, we'll use long division:

First, see how many times 612 fits into 5,945.

Starting from the left, 612 does not fit into 5. We extend it to 59, but 612 doesn't fit into 59 either.

When we take the first three digits, 612 fits into 594 exactly 0 times. So we take one more digit. 612 fits into 5,945 around 9 times because 612 * 9 = 5,508 which is less than 5,945.

Subtract 5,508 from 5,945 to get the remainder. 5,945 - 5,508 = 437.

The quotient is 9 with a remainder of 437, which matches option C: 9 R437.

Answer:

The measure of the smallest angle is 77°

Step-by-step explanation:

* Lats study some facts about the circle

* In any circle; If the vertices of a quadrilateral lie on its

 circumference then the quadrilateral is called a cyclic quadrilateral

- In any cyclic quadrilateral each two opposite angles are supplementary

 that means their sum = 180°

* In any circle; if the vertex of an angle lies on the circumference

 is called an inscribed angle

- The inscribed angle subtended by the opposite arc

- The measure of the inscribed angle = 1/2 the measure of

  the subtended arc

* Now we can solve our question

∵ R , A , T , E all on the the circumference of the circle

∴ RATE is a cyclic quadrilateral

∵ Angle RAT is an inscribed angle subtended by arc RET

∵ The measure of arc RE = 121°

∵ The measure of arc ET = 51°

∴ The measure of arc RET = 121 + 51 = 172°

∵ m∠RAT = (1/2) measure of arc RET

∴ m∠RAT = (1/2) × 172 = 86°

∵ Angle ATE is an inscribed angle subtended by arc ARE

∵ The measure of arc AR = 85°

∵ The measure of arc RE = 121°

∴ The measure of arc ARE = 85 + 121 = 206°

∵ m∠ATE = (1/2) measure of arc ARE

∴ m∠ATE = (1/2) × 206 = 103°

* Now lets find the remainder angles by using cyclic quadrilateral

∵ RATE is a cyclic quadrilateral

∴ m∠RAT + m∠RET = 180°

∵ m∠RAT = 86°

∴ m∠RET = 180 - 86 = 94°

* Similar;

∵ RATE is a cyclic quadrilateral

∴ m∠ATE + m∠ARE = 180°

∵ m∠ATE = 103°

∴ m∠ARE = 180 - 103 = 77°

* The measure of the smallest angle is 77°

Answer: C. (-7x+9)(x-2)

Step-by-step explanation:

1. Factor out the negative sign.

−(7x^2+5x−18)

2. Split the second term in 7x2+5x−18 into two terms.

−(7x^​2​​+14x−9x−18)

3, Factor out common terms in the first two terms, then in the last two terms.

−(7x(x+2)−9(x+2))

4.  Factor out the common term x+2x+2x+2.

−(x+2)(7x−9) or (-7x+9)(x-2)

The correct factorization of the trinomial [tex]-7x^{2} - 5x + 18[/tex] is Option (B) [tex]-1(7x - 9)(x + 2)[/tex]

The given expression is - [tex]-7x^{2} - 5x + 18[/tex]

Factorizing the given expression -

=  [tex]-7x^{2} - 5x + 18[/tex]

=  [tex]-(7x^{2} + 5x - 18)[/tex]

=  [tex]-(7x^{2} + 14x - 9x - 18)[/tex]

=  [tex]-[7x(x + 2) - 9(x + 2)][/tex]

=  [tex]-1(7x - 9)(x + 2)[/tex]

Thus the factorization of the equation is Option (B) [tex]-1(7x - 9)(x + 2)[/tex]

the parallelogram in the image is a rectangle. There are two ways to tell this from the information given: The diagonals of a rectangle bisect each other, but the diagonals in the image do not bisect each other. The opposite sides of a rectangle are congruent, and the sides of the parallelogram in the image appear to be congruent.

The diagonals are perpendicular. In the image, one of the answer choices states that the diagonals are perpendicular, and this is the key giveaway. Diagonals of a rectangle are always perpendicular, so if a parallelogram has perpendicular diagonals, it must be a rectangle.

The diagonals are congruent. Another answer choice states that the diagonals are congruent. While this is also true for rectangles, it is not true for all parallelograms. So, while not all parallelograms with congruent diagonals are rectangles, all rectangles do have congruent diagonals.

Therefore, based on the information given in the image, we can conclude that the parallelogram is a rectangle.

Here are some additional properties of rectangles that you may find helpful:

Opposite sides of a rectangle are equal and parallel.

Opposite angles of a rectangle are equal.

All angles of a rectangle are right angles.

The diagonals of a rectangle bisect each other.

Answer:

180

Step-by-step explanation:

We can use the central angle theorem to understand this problem.

The Central Angle Theorem states that the inscribed angle that fall on the opposite side of the circumference is half of the arc subtended by it.

The angle that is on the opposite side of the circumference is a right angle and thus it measures 90°. This is half of the arc labeled x. So x is twice that of 90.

So, x = 180 degrees

Answer:

180°

Step-by-step explanation:

The angle subtended by the arc is calculated as follows. The angle made at the center by an arc is twice the angle subtended at the circumference.

In the figure the angle subtended at the circumference by the arc is a right angle, that is, 90°  thus the angle that subtends the arc is 2×90=180°

Answer:

Mean: 4, Median: 4, Mode: 4, Range: 5

Step-by-step explanation:

First Put the numbers in order from least to greatest:

2, 2.5, 3.1, 3.7, 4.3, 4.3, 5.1, 7

MEAN: The mean of a group of numbers is the the average so we'll add up all the numbers then divide them by the amount of numbers total. In this case: the um of all the numbers is 32. We are going to now dived 32 by 8, because there are 8 numbers. Using my multiplication facts, I know that 8*4 equals 32, therefore, 32/8 equals 4. So your mean is 4

MEDIAN: Your median is the middle number. This is why it was helpful to put the numbers in alphabetical order. In this one, you will cross off numbers from each end to find the one in the middle. Here is where it would be good to  have a piece of paper and a pencil to cross out the numbers as you go. If you don't have paper, you can use your fingers, which is what I did. Take your finger and put it in front of the end numbers and from there keep going until you have a final middle number. In this case, there are 2 numbers in the middle, so you take the average of those 2 numbers. The two numbers in this problem are 3.7 and 4.3. You ad those together, and you get 8, now you divide 8 by 2 because you have 2 numbers. 8/2 is 4. So your median is 4.

MODE: is the easiest. It's simply the number that appears the most times in the sequence of numbers. so the mode here is 4.3.  

RANGE: Range is the difference between the number with the highest value and the number with the lowest value. The highest value is 7 and the lowest is 2. 7-2 equals 5. So your range is 5

I hope this was helpful!

To calculate the mean, add all numbers together and divide by the count: the mean is 4. Order the numbers to find the median, which is the average of the two middle numbers: the median is also 4. The mode is the most frequent number: in this case, 4.3. Lastly, the range is the difference between the largest and smallest numbers: the range is 5.

To find the mean, median, mode, and range of the given set of numbers (5.1, 3.7, 3.1, 4.3, 7, 2, 4.3, 2.5), let's calculate each one step-by-step.

Mean: Add up all the numbers and divide by the total count:

Mean = (5.1 + 3.7 + 3.1 + 4.3 + 7 + 2 + 4.3 + 2.5) / 8

Mean = 32 / 8 = 4. The mean is 4.

Median: Order the numbers from least to greatest and find the middle number. If there is an even number of data points, take the average of the two middle numbers: 2, 2.5, 3.1, 3.7, 4.3, 4.3, 5.1, 7.

Median is (3.7 + 4.3) / 2 = 4.

Mode: The number that appears most often. In this set, 4.3 appears twice, so the mode is 4.3.

Range: Subtract the smallest number from the largest number in the set: 7 - 2 = 5. The range is 5.

Therefore, the mean is 4, the median is 4, the mode is 4.3, and the range is 5.

Numbers on dice: 1,2,3,4,5,6= 6 numbers

All angles are 60◦, thus all corresponding angles are equal. Since all the sides are equal in each triangle, the ratio of corresponding sides will all be equal.

Final answer:

Francisco's water bottle volume can be calculated using the volume formula for a cylinder. With the given height of 20 cm and radius of 4 cm, the volume comes out to approximately 1.005 liters.

Explanation:

Francisco wants to achieve his daily water intake goal of 2 liters and is curious about the volume of his water bottle with dimensions of a 20 cm height and 4 cm radius. To find the volume of a cylindrical object like a water bottle, we use the formula for the volume of a cylinder, V = πr2h, where V is the volume, r is the radius, and h is the height of the cylinder.

Substituting the given values into the formula:

V = π(4 cm)2(20 cm) = π(16 cm2)(20 cm) = 320π cm3

Since 1 liter is equivalent to 1,000 cubic centimeters (cm3), we convert the volume from cubic centimeters to liters:

V = 320π cm3 × (1 liter/1,000 cm3) ≈ 1.005 liters

Therefore, Francisco's water bottle has a volume of approximately 1.005 liters.
