Answer 6

5+5+5+5=5*4=20

6*5+6*5=6*2+5*2=12+10=22

7+8+9+8=8*2+9+7=16+9+7=32

Answer 7

\(5+5+5+5=5\)X \(4=20\)

\(\left(6+5\right)\)X \(2=22\)

\(7+8+9+8=7+9+\)\(8\)X \(2=32\)

Answer 8

5+5+5+5 = 5x4 = 20

6+5+6+5 = (6x2)+(5x2) = 12+10 = 22

7+ 8 +9+8 = (7+9) + (8x2) = 16+16=16x2=32

Answer 9

5 + 5 + 5 + 5 

= 5 x 4

= 20

6 + 5 + 6 + 5

= 6 x 2 + 5 x 2

= 12 + 10

= 22

7+8+9+8

= 7 + 9 + 2 x 8

= 7 + 9  + 16

= 16 + 16

= 32
