#4\nselect all expressions that are equivalent to 3(2m + 7) - 8(11m + 6).\na. 21 - 82m + 48\nb. 6m + 69 - 88m\nc. -82m - 27\nd. 6m + 21 - 88m + 48
Answer
Explanation:
Step1: Expand the original expression
[ \begin{align*} 3(2m + 7)-8(11m + 6)&=3\times2m+3\times7-8\times11m - 8\times6\ &=6m + 21-88m-48 \end{align*} ]
Step2: Combine like - terms
[ \begin{align*} 6m + 21-88m-48&=(6m-88m)+(21 - 48)\ &=-82m-27 \end{align*} ]
Answer:
C. -82m - 27
