## Tinascott 2 years ago A rectangular box is x feet long and x feet wide. The volume of the box is (4x8 + 3x6) cubic feet. What polynomial represents the height of the box in feet?

1. campbell_st

well the base area is $A= x^2$ multiply length by width and $V = 4x^8+ 3x^6$ take a factor of x^2 out ot the volume $V =x^2(4x^6 + 3x^4)$ now compare it to the volume of a prism V = base area x height you know the base area is x^2 so you should be able to identify the height of the prism

is it = 4x + 3

3. campbell_st

V = base area x height you know the base area is x^2 $V = x^2 \times (4x^6 + 3x^4)$ the height is the other factor... shown above

4x6 + 3x4 yes , thanks
