Which expression is equivalent to `-3\left(2x+5\right)\ +\ 27\ ?`
-5x-8
-6x+12
-2x+12
-6x-8
To find the equivalent expression, we need to distribute the -3 to the terms inside the parentheses:
-3(2x + 5) + 27 = -3(2x) + (-3)(5) + 27 = -6x - 15 + 27 = -6x + 12.
So, the equivalent expression is -6x + 12.
Therefore, the correct answer is -6x+12.
