Question

Which expression is equivalent to -9(x – 4) – 6x?

Question 2 options:

-5x -36


-15x + 36


-15x - 4

Answer 1

= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first

= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x

Combine like terms
= (-9x-6x) + 36

= -15x + 36

The middle choice is the answer:
-15x + 36

Hope this helps! :)
