Answer:
1/8
Step-by-step explanation:
I'm going to try to explain this as easy as possible. What I did was take the original shape and divide it by the new shape. For this question, I solved it by dividing 32(the original base) by 4(the new base) and got 8. So the scale factor of the reduction was 1/8.
To factor a number out of an expression means to divide each term of the expression by that number.
So, if you want to factor
from the expression
, you'll write it as

So, in your case, when you divide both terms by -5 you get

So, the expression becomes

C is the answer
Hope this helps
One would be 2pi - 5pi/18 = 31pi/18
another positive one is 31pi/18 + 36pi/18 = 67pi/18
and the negative angle is -5pi/18 - 36pi/18 = -41pi/18
The answer is b
