A classroom has a volume of x3 + 5x2 – 2x – 24 ft3 and the height is x – 2 ft. The floor is represented by what polynomial? x2 + x + 7 x2 – 7x + 7 x2 + x – 12 x2 + 7x + 12

    volume = area of floor * height

    I think that you mean "area of the floor".

    area of floor= volume/ height

    For the area of floor, divide x - 2 from that polynomial.

    For that, do synthetic division, long division or any other crappy method.

    \[\frac{ x^3+5x^2-2x-24 }{ x-2 }\] hope that helps you Lindsey

    I'd recommend synthetic division.
