The length of a rectangle is represented as l(x)= 4x-1. The width of the rectangle is represented as w(x)= 2x+3. What is the area, A(x), of the rectangle?
The area of a rectangle is equation to its length multiplied by its width:
Substituting what we know:
Therefore, the equation for the area of the rectangle is `8x^2+10x-3`
