What is the sum of the polynomials?<br><br> (7x^3 – 4x^2) + (2x^3 – 4x^2)
AVprozaik [17]
(7x^3 – 4x^2) + (2x^3 – 4x^2)
Add 2x^3 to 7x^3
(9x^3 - 4x^2) + (-4x^2)
Add -4x^2 to -4x^2. This would be the same as subtracting 4x^2 from -4x^2
Final Answer: 9x^3 - 8x^2

*The answer cannot be broken down anymore. It's in it's simplest form.

What use the perimeter of the figure below
morpeh [17]

Answer:

C

Step-by-step explanation:

The perimeter would be 2*(4(2x+1) + 3(x+4)) because the right side length and the top side length are known. The left side length must equal the right side length and the bottom side length must equal the top side length. So the answer must be:

2*(4(2x+1) + 3(x+4)) = 2*(8x+4+3x+12) = 2*(11x+16) = 22x+32

C. 22x+32

A raffle prize of 14x^2/15dollars is to be divided among 7x people. Write an expression for the amount of money that each person
vladimir2022 [97]

For this case we must divide the following expression:

\frac {\frac {14x ^ 2} {15}} {7x}

And in this way we get the amount of money that each person will receive.

Then applying double C we have:

\frac {14x ^ 2} {15 * 7x} =\\\frac {14x ^ 2} {105x} =\\0.133x

Thus, each person has 0.133x of money!

Answer:

0.133x

puteri [66]

Answer:

Distance between Alan and Alissa (ft/s)

Time (s)

Step-by-step explanation:

In this example, since Alan and Alissa are both traveling at a constant rate, their velocity is not a varying quantity. However, the distance between Alan and Alissa is varying as a function of time at a rate of 9 feet per second. Since the distance is a function of time, time is also a varying quantity.

Therefore, the only varying quantities are the distance between Alan and Alissa (ft/s) and the time (s).
