Question

- 18 * [(-7) + 3] = (-18) *x + (-18)*3​

Answer 1

Answer:

Step-by-step explanation:

By using distributive law

ax(b+c)  = axb + axc

a) 18 x[7+(-3)] = 18x7  + 18 x (-3)

     18 x 4          = 126 - 54

         72     =  72     so it is true

Answer 2

18 x [7 +(-3)] = [18 x 7] +[18 x (-3)]

18× [7 - 3] = 126 + [-54]

18× 4 = 126 - 54

72 = 72

LHS = RHS
