Question

Please help me medal will be awarded
A classroom has a volume of x3 + 6x2 – 1x – 30 ft3 and the height is x – 2 ft. The floor is represented by what polynomial?

x2 + 2x – 15

x2 + 8x + 15

x2 + 2x + 8

x2 – 8x + 8

Answer 1

this is a rectangular paralellopipe
volume = area of base * height

Answer 2

soor hold have to change the question

Answer 3

by the floor, they mean the area of base
\[
x^3+6x^2-x-30=A(x)\times(x-2)\\
A(x)=\frac{x^3+6x^2-x-30}{x-2}
\]
you can solve this by long-division or by synthetic division
