Answer:
I think it would be 5(4b+7)
Step-by-step explanation:
I divided both terms by 5.
You could rewrite

as

and be tempted to cancel out the factors of

. But this cancellation is only valid when

.
When

, you end up with the indeterminate form

, which is why

is not a zero.
If r(x)= 11x, and c(x)=6x +20, then just put that into the equation.
So instead of p(x) = r(x) - c(x)
I would be p(x) = 11x - 6x + 20
Now solve.
p(x) = 5x + 20 is your final answer, so A.
Answer:
The answer is A - symmetry.
None of the other options really have bearing in relation to the question.
