Q:

-2(7a+4b)-6c= Simplify

Accepted Solution

A:
Answer:Because of the minus sign 2 becomes - 2 The answer is -2 Multiply a and 7 Multiply a and 1 The a just gets copied along. The answer is a a 7*a evaluates to 7a Multiply b and 4 Multiply b and 1 The b just gets copied along. The answer is b b 4*b evaluates to 4b 7*a+4*b evaluates to 7a+4b Multiply -2 by 7a+4b we multiply -2 by each term in 7a+4b term by term. This is the distributive property of multiplication. Multiply -2 and 7a Multiply 1 and a The a just gets copied along. a -2 Γ— 7a = -14a Multiply -2 and 4b Multiply 1 and b The b just gets copied along. b -2 Γ— 4b = -8b -2*(7*a+4*b) evaluates to -14a-8b Multiply c and 6 Multiply c and 1 The c just gets copied along. The answer is c c 6*c evaluates to 6c The answer is -14a-8b-6c -2*(7*a+4*b)-6*c evaluates to -14a-8b-6c The final answer is -14a-8b-6cStep-by-step explanation:Please mark brainliest and have a great day!
