Given
[tex]\begin{gathered} \text{Volume =-5x}^5-1 \\ \text{height = 5x+5} \end{gathered}[/tex]
The formula for the volume of a rectangular prism
[tex]\text{Volume}=\text{base area }\times height[/tex]
Make area subject of the formula
[tex]\begin{gathered} \text{Base area=}\frac{volume}{\text{height}} \\ \\ \text{Base area=}\frac{-5x^5-1}{5x+5} \end{gathered}[/tex]
Using the long division method
The final answer is
[tex]-x^4+x^3-x^2+x-1+\frac{4}{5x+5}[/tex]
Option B
