Question

A contractor built a basement for a new home. The volume of the rectangular basement shown at the right is represented by the expression 3x3+6x2-30x. If the height of the basement is 3x, what is the area of its base?

Answer 1

I did the math and the other answer is right !

Answer 2

C. x^2+2x-10

Explanation:

Volume of a Rectangular Prism = LWH

We have the height so we can simplify by dividing it out of the total volume

Then you get x^2+2x-10.

Since the area of the base is LW, that is your answer
