The volume of a rectangular prism is represented by the expression x3 + 5x2 - 8x -
48 If the length is (x – 3) and the height and
width are equal, what is the width of the prism?
(x + 4)
(x-4)
(x - 2)
(x + 2)
plsss hurry

Step-by-step explanation:

This question is essentially asking: . Find .

The left hand side can be factored into by the rational root theorem and polynomial division.

We can then divide both sides of the equation to get .

Finally, we take the square root of both sides to obtain .

So, the answer is

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above
