The given expression is simplified as x² + 3x - 4.
What is an Algebraic expression?
An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is as below,
((4x²+ 12x - 16) / (2x + 10)) / ((6x + 24) / (x ²+ 9x + 20))
It can be simplified as,
((4x²+ 12x - 16) (x ²+ 9x + 20)) / (2x + 10) (6x + 24)
Now, (4x²+ 12x - 16) and (x ²+ 9x + 20) can be factorised as,
4x²+ 12x - 16 = 4x²+ 16x - 4x - 16
= 4x(x + 4) - 4(x + 4)
= (4x - 4) (x + 4)
And, x ²+ 9x + 20 = x ²+ 5x + 4x + 20
= x(x + 5) +4(x + 5) = (x + 4) (x + 5)
Substitute the factors to get the expression as,
(4x - 4) (x + 4) (x + 4) (x + 5) / (2x + 10) (6x + 24)
= (4x - 4) (x + 4) (x + 4) (x + 5) / 2 × 2(x + 5) (x + 4)
= (4x - 4) (x + 4) / 4
= 4(x - 1) (x + 4) / 4
= (x - 1) (x + 4)
= x² + 3x - 4
Hence, the given expression can be simplified as x² + 3x - 4.

For three consecutive years, Sam invested some money at the start of the year. The first year, he invested x dollars. The second year, he invested $2,000 less than 5/2 times the amount he invested the first year. The third year, he invested $1,000 more than 1/5 of the amount he invested the first year.
During the same three years, Sally also invested some money at the start of every year. The first year, she invested $1,000 less than 3/2 times the amount Sam invested the first year. The second year, she invested $1,500 less than 2 times the amount Sam invested the first year. The third year, she invested $1,400 more than 1/4 of the amount Sam invested the first year.
If Sam and Sally invested the same total amount at the end of three years, the amount Sam invested the first year is $ ???, and the amount Sally invested the last year is $ ???
Answer:
The first year Sam invested $2,000. The third year sally invested $1,900.
Step-by-step explanation:
Let $x be the amount of money Sam invested the first year. The second year, he invested $2,000 less than 5/2 times the amount he invested the first year, then the second year he invested
[tex]\$\left(\dfrac{5}{2}x-2,000\right).[/tex]
The third year, he invested $1,000 more than 1/5 of the amount he invested the first year, then the third year he invested
[tex]\$\left(\dfrac{1}{5}x+1,000\right).[/tex]
During three years Sam invested
[tex]\$\left(x+\dfrac{5}{2}x-2,000+\dfrac{1}{5}x+1,000\right)=\$\left(\dfrac{37}{10}x-1,000\right).[/tex]
The first year, Sally invested $1,000 less than 3/2 times the amount Sam invested the first year, then the first year she invested
[tex]\$\left(\dfrac{3}{2}x-1,000\right).[/tex]
The second year, she invested $1,500 less than 2 times the amount Sam invested the first year, then the second year she invested
[tex]\$(2x-1,500).[/tex]
The third year, she invested $1,400 more than 1/4 of the amount Sam invested the first year, then the third year she invested
[tex]\$\left(\dfrac{1}{4}x+1,400\right).[/tex]
During three years Sally invested
[tex]\$\left(\dfrac{3}{2}x-1,000+2x-1,500+\dfrac{1}{4}x+1,400\right)=\$\left(\dfrac{15}{4}x-1,100\right).[/tex]
If Sam and Sally invested the same total amount at the end of three years, then
[tex]\dfrac{37}{10}x-1,000=\dfrac{15}{4}x-1,100,\\ \\\dfrac{37}{10}x-\dfrac{15}{4}x=1,000-1,100,\\ \\-\dfrac{1}{20}x=-100,\\ \\x=\$2,000.[/tex]
Thus,
[tex]\$\left(\dfrac{1}{4}\cdot 2,000+1,400\right)=\$1,900.[/tex]

(In terms of pi )what's the surface area of a cylinder with a 14cm diameter and a heigth of 18cm.
ive done the math and got 1099 or something but that isnt one of the options on my assignment.
Answer:
= 1099 cm^2
Step-by-step explanation:
The surface area of a cylinder is found by using the formula
SA=2πrh+2πr^2
We know the diameter. To find the radius, we take the diameter and divide by 2.
r =d/2
r =14 cm/2 = 7 cm
h = 18 cm
Substituting what we know
SA = 2 * pi * 18 * 7 + 2 * pi * (7)^2
= 252 *pi + 2* pi *49
= 252 pi + 98 pi
= 350 * pi
Let pi be approximated by 3.14
SA = 350 * 3.14
= 1099 cm^2

What are the quotient and remainder of (3x^4-2x^3+7x-4)/(x-3)
Answer: Remainder: 206
Quotient: 3x³+7x²+21x+70 + [tex]\frac{206}{x-6}[/tex]
Step-by-step explanation: You can either use long division or synthetic division. I will use synthetic division: 3 | 3 -2 0 7 -4... the remainder is 206 and the quotient is 3x³+7x²+21x+70 + 206/x-6
The remainder is 206 and the quotient is ([tex]3x^{4} - 2x^{3} + 7x -4[/tex] -206) /(x - 3)
What is quotient in a division?A result obtained by dividing one quantity by another is called a quotient.
What is remainder in a division?Remainder is the value left after the division.
How to find the quotient and remainder of the division?We know that, if (x - h) divides a function f(x) then f(h) is the remainder.∴ Here the remainder will be putting x = 3 in the dividend.
So, remainder = [tex]3(3)^{4} - 2(3)^{3} + 7(3) - 4[/tex] = 206
We can get the quotient by the quotient remainder rule which saysin a division, dividend is equal to divisor multiplied by quotient plus remainder.
Let the quotient be Q(x)
Here, we can write,
[tex]3x^{4} - 2x^{3} + 7x -4[/tex] = (x - 3)Q(x) + 206
⇒ Q(x) = ([tex]3x^{4} - 2x^{3} + 7x -4[/tex] -206) / (x - 3)
So, the required quotient is ([tex]3x^{4} - 2x^{3} + 7x -4[/tex] -206) / (x - 3)

Given m(x)=3x-2 and p(x)=-4+2, what is (m-p)(x)?
Final answer:
(m-p)(x) represents the subtraction of function p(x) from m(x). Assuming p(x) is -4x + 2, (m-p)(x) simplifies to 7x - 4.
Explanation:
To calculate (m-p)(x), we need to subtract the function p(x) from the function m(x).
Given m(x) = 3x - 2 and noting there seems to be an error in p(x), as it should likely be a function of x, let's assume the student meant p(x) = -4x + 2 based on the pattern of the provided information.
The subtraction of these two functions is performed as follows:
m(x) - p(x) = (3x - 2) - (-4x + 2)
Simplify by distributing the negative sign through the second polynomial:
(3x - 2) + 4x - 2 = 3x + 4x - 2 - 2
Combine like terms:
7x - 4
So, (m-p)(x) = 7x - 4.

The doctor orders2cc of 2% lidocaine to be use as a loca anesthetic how many milliliter s will you draw
one may note that 1 CC, Cubic Centimeter, or 1 cm³, is actually equivalent to 1 mL, milliliter.
so 2 cc = 2 mL.
Answer:
2 mL
Step-by-step explanation:
Here cm³ and mL are units of volume i.e., the three dimensional space enclosed by plane surfaces. m³ is the SI unit of volume. Liter (L) is also an accepted unit where
1 L = 0.001 m³
So 1 ml = 0.001 × 10⁻³ m³
1 mL³ = 10⁻⁶ m³ (1)
1 m³ = 10⁶ cm³
1 cm³ = 10⁻⁶ m³ (2)
From equation 1 and 2
1 mL = 1 cm³
1 mL = 1 cc
2 cc = 2 Cubic centimeter = 2 cm³
1 cc = 1 mL
So,
2 cc = 2 mL
Write the equation in logarithmic form. N^4/3=m. Please show all your steps!!
Answer:
[tex]log_n(m)= \frac{4}{3}[/tex]
Step-by-step explanation:
N^4/3=m
[tex]n^{4/3}=m[/tex]
We need to write the equation in logarithmic form
we take log on both sides
[tex]log(n^{4/3})=log(m)[/tex]
We apply log property to remove the exponent 4/3
As per log property we can move exponent before log
log(a^m) = m log (a)
So our equation becomes
[tex]\frac{4}{3}log(n)=log(m)[/tex]
Now we divide both sides by log(n)
[tex]\frac{4}{3} =\frac{log(m)}{log(n)}[/tex]
Now we apply change of base formula
log(a)/ log(b)= log_b(a)
[tex]\frac{4}{3} =log_n(m)[/tex]
So log form is
[tex]log_n(m)= \frac{4}{3}[/tex]
To convert [tex]N^{4/3}[/tex] = m to logarithmic form, identify the base (N), the exponent (4/3), and the result (m). The logarithmic form is [tex]log_N(m)[/tex] = 4/3.
To convert the given equation [tex]N^{4/3}[/tex] = m into logarithmic form, we'll follow these steps:
Identify the base, which is N in this case.The exponent in the equation is 4/3.The result is m.The general logarithmic form of the equation aᵇ = c is [tex]log_a(c)[/tex] = b.
Applying this to our equation:
The base a is N.The result c is m.The exponent b is 4/3.Hence, the logarithmic form of the equation [tex]N^{4/3}[/tex] = m is:
[tex]log_N(m)[/tex] = 4/3In geometry vertical angles are congruent, meaning they have the same degree measure. You see these when two straight lines form and X shape. Angles that are opposite one another are called vertical angles. If two of these congruent angles have the same degree measure and angle 1 is (3x+10) degrees and angle 2 is (5x-4) degrees, set the expressions equal to one another and find the degree measure. Hint: Don't just solve for the variable X, you have to solve for degree measure by substitution. Do so in both expressions as a way to check your work. The degree measures should be the same if you solved for the variable correctly
Answer:
The two angles are each 31 degrees.
Step-by-step explanation:
Find x
3x + 10 = 5x - 4 Add 4 to both sides3x + 10 + 4 = 5x - 4 + 43x + 14 = 5x Subtract 3x from both sides.3x - 3x + 14 = 5x -3x14 = 2x Divide by 214/2 = 2x/2 7 = x Switch x = 73x + 10
3*7 + 1021 + 10 315x - 4
5(7) - 4 35 - 431By setting 3x+10 equal to 5x-4, we find x=7. Substituting this value back into the expressions for both angles 1 and 2, we find that both angles measure 31 degrees, confirming that our solution is correct.
Explanation:The question asks you to solve for the degree measure of both angles 1 and 2, which are represented by the expressions (3x+10)° and (5x-4)° respectively. Because these angles are vertical, we know that they are congruent, or equal in measure.
Therefore, we can form an equation by setting the two expressions equal to each other and then solving for x:
(3x+10) = (5x-4)
Subtracting 3x from both sides yields:
10 = 2x - 4
Then, adding 4 to both sides, we get 14 = 2x. Dividing both sides by 2, we find x = 7.
To check our work, we substitute x = 7 into the original equations for both angle 1 and angle 2:
Angle 1: 3(7) + 10 = 31°
Angle 2: 5(7) - 4 = 31°
As you can see, the degree measures are the same, which verifies that we solved for the variable correctly.

solve the system by the elimination method
Answer:
x=2, y=2
(2,2)
Step-by-step explanation:
To solve by elimination, we need to have on variable an its coefficient be the opposite of the other
I will multiply the second equation by 2 to make 2x become 4x to eliminate the x variable
2(2x+4y) = 12*2
4x+8y = 24
Now add the first equation with the modified second equation
-4x - 2y = -12
4x +8y =24
-------------------
6y = 12
Divide each side by 6
6y/6 = 12/6
y =2
Now we need to find x
2x+4y = 12
Substitute in y=2
2*x + 4*2 = 12
2x+8 = 12
Subtract 8 from each side
2x +8-8 = 12-8
2x=4
Divide each side by 2
2x/2 =4/2
x=2
Which situation is best represented by the following equation? 40w + 12.50 = 492.50
Answer:
Step-by-step explanation:
She paid $40 each week, hence the "w" next to 40. She then paid $12.50 so both $40w and $12.50 would equal to $492.50. So she paid $492.50 in all for the class.
Now the w would equal, 12. Multiply 40 x 12 and it'd equal 480.
Then you add the additional $12.50 she paid for the registration & it'd equal to $492.50.
Hope That Helps!
To solve for w in the equation 40w + 12.50 = 492.50, subtract 12.50 from both sides of the equation and then divide both sides by 40.
Explanation:To solve for w, we need to isolate it on one side of the equation. We can do this by subtracting 12.50 from both sides of the equation:
40w + 12.50 - 12.50 = 492.50 - 12.50
This simplifies to:
40w = 480
Next, divide both sides of the equation by 40:
w = 480 / 40
w = 12
Therefore, the equation represents a situation where w is equal to 12.
