Question

The volume of a rectangular prism is represented by the function x^3 + 11x^2 + 20x – 32. The width of the box is x – 1 while the height is x + 8. Find the expression representing the length of the box.

Answer 1

can u divide two polynomials??
like can u divide your volume function by x-1 or x+8 ??

Answer 2

yes

Answer 3

good,now volume = length * width * height
so length = volume / (height * width)
so first divide volume function by width function
then divide the answer u get by height function
the final answer will be length function.....

Answer 4

x+4?

Answer 5

absolutely correct :)

Answer 6

thank you!!(:
