Answer:
r = 1
Step-by-step explanation:
In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.
Distributive Property:
a(b+c) = ab + ac
Now, lets solve this:

As we have seen the value of r is "1"
I believe the answer is b because u need to combine like terms and 6c+2c+5c is 13c.
X = 140
You do 110 + 30 and that gives you 140. Hope it helped!
