1) (4 + 2) x 3 = 4 x 3 + 2 x 3 = 18

2) (6 + 9 ) x 10 = 6 x 10 + 9 x 10 = 150

3) 5 x ( 3 + 4 ) = 5 x 3 + 5 x 4 = 35

4) (3 + 9) x 9 = 3 x 9 + 9 x 9 = 108

5) 2 x (5 + 7) = 2 x 5 + 2 x 7 = 24oa + b + c + d + e = x

e + d + c + b + a = x

b + c + e + a + d = x

c + d + b + a + e = x

d + e + b + c + a = x.
