A) $2 a-6 b+5 c+6 d$
B) $2 a-6 b-3 c-6 d$
C) $2 a-6 b-5 c+6 d$
D) $2 a-6 b-5 c-6 d$

Question

Quizplus · Accepted Answer

To subtract the given expressions, distribute the negative sign through the second set of parentheses and then combine like terms: $2a + 2b - c - (8b + 4c + 6d) = 2a + 2b - c - 8b - 4c - 6d = 2a - 6b - 5c - 6d$.

Subtract - (2a+2 b−c)−(8 b+4c+6 d)(2 \mathrm{a}+2 \mathrm{~b}-\mathrm{c})-(8 \mathrm{~b}+4 \mathrm{c}+6 \mathrm{~d})(2a+2 b−c)−(8 b+4c+6 d) A) 2a−6b+5c+6d2 a-6 b+5 c+6 d2a−6b+5c+6d
