(07.02) the following table shows the length and width of two rectangles: length width rectangle a 2x + 8 x − 1 rectangle b 3x + 5 2x − 2 which expression is the result of the perimeter of rectangle b minus the perimeter of rectangle a? (1 point) 16x + 20 2x − 4 4x − 8 8x + 10

Step-by-step explanation:

Rectangle A

The length of this rectyangle is:  

The width of this rectangle is:  

Perimeter of rectangle A

The perimeter is given by:

We substitute the expressions and simplify:

Rectangle B.

The length of this rectangle is:

The width of this rectangle is :

Perimeter of rectangle B

We apply the formula for perimeter again to obtain;

Perimeter of rectangle B minus perimeter of rectangle A

d) -1
