Subtract the following polynomials, then place the answer in the proper location on the grid.
Answers
To subtract polynomials, align the terms and subtract their corresponding coefficients.
Explanation:Subtracting polynomials involves subtracting the corresponding terms from each other. Start by aligning the like terms and then subtract their coefficients. If there are any terms that cannot be simplified further, leave them as they are in the final answer. For example, if we have (3x^2 + 2x - 5) - (2x^2 - 3x + 4), we align the terms and subtract them to get (3x^2 - 2x^2) + (2x + 3x) + (-5 - 4) = x^2 + 5x - 9.

Sandy can jog 3 2/5 miles in 5/6 hour. Find her average speed in miles per hour.
Answers
(17/5 mi)/(5/6 hr) = 102/25 mi/hr
Answer:
[tex]4\frac{2}{25}[/tex] miles per hour
Step-by-step explanation:
Sandy can jog a distance [tex]3\frac{2}{5}[/tex] miles or [tex]\frac{17}{5}[/tex] in the duration = [tex]\frac{5}{6}[/tex] hours
Since speed = [tex]\frac{distance}{time}[/tex]
We plug in the values of distance and time in the formula of speed.
Speed = [tex]\frac{\frac{17}{5}}{\frac{5}{6}}[/tex]
= [tex]\frac{17}{5}[/tex] × [tex]\frac{6}{5}[/tex]
= [tex]\frac{102}{25}[/tex]
= [tex]4\frac{2}{25}[/tex] miles per hour
Her average speed is [tex]4\frac{2}{25}[/tex] miles per hour.

Explain how to solve rate of wind and rate of current problems
Answers
Final answer:
To solve rate of wind and current problems, analyze the given velocities, represent them as vectors, perform vector addition, and apply trigonometry to find the effective velocity or required direction. This method helps in determining the true path of a vehicle influenced by wind or current.
Explanation:
To solve rate of wind and rate of current problems, it is essential to understand vectors and relative motion. Here is a step-by-step approach to solving these problems:
Analyze the question to understand what is being asked, including the direction and magnitude of both the wind/current and the vehicle (aircraft, boat, etc.).Represent the given velocities as vectors. The wind or current velocity should be added to the vehicle’s velocity to determine the resulting path.Apply the vector addition concept to calculate the effective velocity of the vehicle relative to the Earth. This might include using trigonometric functions to resolve vectors into components.Once the effective velocity is known, use it to solve for other quantities like travel time, distance, or the required heading to reach a certain destination.For example, if an aircraft flies with a wind velocity of 200 km/hr blowing from the south and its relative velocity with respect to wind is 1000 km/hr, the direction in which the aircraft should fly to reach a north-eastern destination can be calculated using vector addition and trigonometry.
-3 times what equals 9
Answers
x = 9 / (-3)
x = -3 <== so -3 * -3 = 9
The value to fill in the blank is -3.
So, -3 x -3 = 9.
We have,
To solve the equation -3 x __ = 9, we need to find the value to fill in the blank that makes the equation true.
Let's denote the value we need to find as "x".
When we multiply -3 by "x", it means we are adding -3 to itself "x" times.
So, the equation becomes -3 times "x" equals 9:
-3x = 9.
To solve for "x", we can divide both sides of the equation by -3:
-3x / -3 = 9 / -3
This simplifies to:
x = -3
Therefore,
The value to fill in the blank is -3. So, -3 x -3 = 9.

x = + - 8
hope it helps
Answer:
We are asked to find all the values of x on the number line that satisfies the given quadratic equation:
[tex]x^2=64[/tex]
We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.
on taking the square root on both the side of the equation we obtain:
[tex]x=\pm 8[/tex]
Hence we get two points on the number line.
x=8 and x= -8.

Twenty-one out of 70 customers at the restaurant ordered dessert. What percentage of the customers did not order dessert?
Answers
To find your answer you must subtract first:
70 - 21 = 49
Now, how much percent is 49 of 70?
49/70 = 0.7000
0.7000 * 100 = 70.00%
49 is 70% of 70.
I really hope this helped you! :)
To check your answer: (70 × 70.00)/100 = 49
70 - 21 = 49
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
[tex] \frac{49}{70} [/tex] = [tex] \frac{x}{100} [/tex]
Cross multiply.
70x = 4,900
Now, all you would need to do is isolate the x. To do this, you would divide both sides by 70.
x = 70
x = 70%
So, 70% of the customers ordered dessert.

Number 18 pls help me
Answers
Following PEMDAS, we first focus on the parenthesis. So we simplify 9-3 to get 6
So we go from
18*4^2+(9-3)^2
to
18*4^2+6^2
The next step is applying exponents. In this case, squaring the terms, so we go from
18*4^2+6^2
to
18*16+36
Next is multiplying
18*16+36
turns into
288+36
Finally, add up 288 and 36 to get 288+36 = 324
That confirms that Lila is correct
----------------------
The error that Rob made is that he computed 18*4^2+9^2-3^2 but it is NOT correct. Saying (x-y)^2 = x^2-y^2 isn't a true equation for all x and y. Again you have to simplify what is in the parenthesis first, and then you can square it. Or you must use the FOIL rule to expand out (9-3)^2

A triangle has the following angle measures: 125°, 15°, and 40°. Which of the following statements best describes its drawing?
A)It is impossible to construct a triangle with these angle measures.
B)There is one possible triangle with these angle measures.
c)There are many possible triangles with these angle measures.
D)There are many possible similar triangles with these angle measures.
Answers
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Measures of angles are as follows:
125°, 15°, 40°
As we know the sum of all angles in a triangle is supplementary i.e. 180°.
∠A+∠B+∠C=180°
125°+15°+40°=180°
Therefore, it is satisfying the angle sum property.
So, it can form a triangle.
Now, we will check for uniqueness.
As similar triangles need two angles to be equal by AA criteria , their sides can vary with two equal angles.
Hence, there is possibility to have many possible similar triangles with angle measures.
Therefore, Option 'D' is correct.
