Answer:

See below

Explanation:

1. Perimeter is the sum of all sides.

(x+4)+(x+4)+(2x-8)+(2x-8)

(x+4)+(x+4) = 2x+8

(2x-8)+(2x-8) = 4x-16

2x+8 + 4x-16 =

6x-8

2.

4x-5 Sat

3x-10 Sun

(4x-5)-(3x-10)

4x-3x = x

-5--10 = 5

x+5

3. Total, so add

8x+16 Sat

7x-9 Sun

(8x+16) + 7x-9

8x+7x=15x

16-9=7

15x+7
