Use the distributive property to remove parentheses.
-9(5x + 5y + 2)
A) 45x + 45y + 2
B) 45x + 5y + 18
C) 45x + 45y + 18
D) 45x + 5y + 2

Question

Quizplus · Accepted Answer

To use the distributive property, we need to multiply the number outside the parentheses (9) with each term inside the parentheses. 
So, we get:
9(5x) + 9(5y) + 9(2)
= 45x + 45y + 18 
Therefore, the correct choice is C. Using the distributive property, we can distribute the 9 to each term inside the parentheses. 
9(5x + 5y + 2) = (9*5x) + (9*5y) + (9*2) 
This simplifies to: 
45x + 45y + 18 
So the answer is choice C.
