there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
Remember that for a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we know that the area is:
[tex]A = 4x^2 + 12x[/tex]
We can factorize that expression into:
[tex]A = x*(4x + 12)[/tex]
So there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
