Question

See comments for question.

Answer 1

\[V=x^3+13x^2+34x-48\]

Answer 2

Volume of box = width * length * height
You're given:
Width: x+6
Height: x+1
Length: L

\[(x+6)(x+1)(L) = x ^{3}+13x ^{2}+34x-48\]

Answer 3

\[L = \frac{ x ^{3}+13x^{2}+34x-48 }{ (x+1)(x+6) }\]

Answer 4

Expand the denominator, then do long division

Answer 5

Oh ok, I see how to set it up now. Then you just do long or synthetic division yes?

Answer 6

Yup

Answer 7

ok thanks! I just couldn't get the setup.

Answer 8

no problem
