Question

Verify the following:
(D) 18 x [7 +(-3)] = [18 x 7] + [18 (-3)]
​

Answer 1

Step-by-step explanation:

a.    18 × [7-3] = 126 + [-54]        (+×- = -)

       18 × 4 = 126-54

       72 = 72

    therefore lhs = rhs

b.     21×[-10] = [84]+[126]             ( -×- = +)

       -210 =/= 210

    therefore lhs =/= (is not equal to) rhs
