which expressions are equivalent to 4m - 2 + (-8m)? choose all answers that apply: a -2(4m + 1) + 4m b 2(2m - 1) - 8m c none of the above
Answer
Explanation:
Step1: Simplify the given expression
$4m - 2+(-8m)=4m - 8m - 2=-4m - 2$
Step2: Simplify option A
$-2(4m + 1)+4m=-8m-2 + 4m=-4m - 2$
Step3: Simplify option B
$2(2m - 1)-8m = 4m-2 - 8m=-4m - 2$
Answer:
A. $-2(4m + 1)+4m$, B. $2(2m - 1)-8m$
