Answer 1

Answer:

A) 7956

B) -6900

C) 700000

Step-by-step explanation:

A) Distributive Property

78 × 102 = (80+[-2])×(100+2) = (80×100)+(-2×2) = 8000 - 4 = 7956

B) Distributive Property

[-69]×94+[-69]×6 = (-69) × (94 + 6) = -69×100 = -6900

C) Commutative Property

4×[-8]×25×7×[-125] = (-8×-125)×(4×25)×7 = 1000×100×7 = 700000
