## lindseyharrison 2 years ago 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

1. arlen

volume = area of floor * height

2. ParthKohli

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

3. arlen

area of floor= volume/ height

4. ParthKohli

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

5. ParthKohli

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

6. arlen

lindsey you there?

7. lindseyharrison

yes i am

8. arlen

cool....you can do this now...

9. arlen

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

10. lindseyharrison

A?

11. arlen

no

12. Dallasb22

Arlen, is it B?

13. lindseyharrison

It's C!

14. CliffSedge

I'd recommend synthetic division.

15. arlen

yes

16. jim_thompson5910

it's not C

17. arlen

sorry it's D
