Answer: the height is 3x^2 + 5x + 4
Explanation:
The expression for the area of the rectangle is given as
3x^3 - x^2 - 6x - 8
The length of the base is represented by x - 2
Height = Are/base
= 3x^3 - x^2 - 6x - 8/x - 2
We would determine the height by using the long division method. The working is shown in the attached photo
