I am so lost, please help. The length of a rectangle is x inches and its width is 4 inches more than two thirds of its length. What is the perimeter of the rectangle in inches?
2L + 2W = P
If L = x, then W = 2/3x + 4
2x + 2(2/3x+4) = P
2x + 4/3x + 8 = P
Combine like terms.
If L = x, then W = 2/3x + 4
2x + 2(2/3x+4) = P
2x + 4/3x + 8 = P
Combine like terms.
