Answer 1

Answer:

-57 is the answer of this question

Answer 2

Answer:

72

Step-by-step explanation:

Q2) Verify the following:

(a) 18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]

(b) (–21) × [(– 4) + (– 6)] = [(–21) × (– 4)] + [(–21) × (– 6)]

solution 2 (a) 18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]

18 × [4] = [18 × 7] + [–54]

18 × [4] = 126 –54

72=72

LHS=RHS

hence verified!
