3 x 42

4 x 32

3 (40 + 2)

4x (30 + 20)

(3 x 40) + (3 x 2)

(4 x 3) + (4 x 2)

Answer 1

Answer: 3 x 42 , 3(40 +2), (3 x 40) + (3 x 2)

Explanation:

3 x 42 = 126

4 x 32 = 128

3 ( 40 + 2) = 3 x 40 + 3 x 2 = 126

4x ( 30 + 20) = 4x x 30 + 4x x 20 = 200x

(3 x 40) + (3 x 2) = 126

( 4 x 3) + ( 4 x 2) = 20
