Which expression is equivalent to -3(2x+5) +27
A. -5x - 8
B. -6x + 12
C. -2x + 12
D. -6x - 8
To expand the expression -3(2x + 5), we distribute the -3 to both terms inside the parentheses:
-3(2x + 5) = -3(2x) - 3(5) = -6x - 15
So the original expression -3(2x+5) + 27 is equivalent to -6x - 15 + 27.
To simplify the expression, we combine like terms:
-6x - 15 + 27 = -6x + 12
Therefore, the expression -3(2x+5) + 27 is equivalent to -6x + 12.
The answer is B. -6x + 12.
