Asquare can be changed into a rectangle by increasing the length of the square by 5 units and increasing the width by 3 units. which expression represents the area of the rectangle in square units?

To represent the area of this rectangle, you will write expressions that represents the new length and the new width. x Will represent the original side length.

l = x + 5
w = x - 3

A= lw
(x + 5)(x - 3)
This becomes x^2 + 2x - 15.

Really long apparently
