Rectangle ABCD has a length represented by the expression 12x + 9 and a width represented by the expression 7x - 2. Rectangle PQRS has a length represented by the expression 2x +3 and a
width represented by the expression x + 4. Which of the following expressions can be used to
represent the difference in the perimeters of Rectangle ABCD and Rectangle PQRS?
a.32x
b. 23x + 4
C.32x - 10
d. 7x + 3

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
