Simplify the expression: -3 (-5y -6) -4
A. 11y + 14
B. 11y + 14
C. 15y + 14
D. 15y + 2
To simplify the expression -3(-5y - 6) - 4, we first distribute the -3:
-3*(-5y) = 15y
-3*(-6) = 18
So the expression becomes: 15y + 18 - 4
Next, combine the constants:
15y + 18 - 4 = 15y + 14
Therefore, the simplified expression is 15y + 14. So the correct answer is C. 15y + 14.
