Answer:
9x - 45
Step-by-step explanation:
To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.
-9(-x + 5)
-9 · -x = 9x
-9 · 5 = -45
Now we add our products together.
9x + -45
Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.
9x - 45
