Question

The volume of a rectangular prism is represented by the function x3 + 9x2 + 6x – 16. The length of the box is x + 2 while the height is x + 8. Find the expression representing the width of the box.

Answer 1

given equation can be written as
\[(x+2)(x+8)(x-1)\]
volume of rectangle prism is lenght*width*height

so, width = \[x-1\]
