Question

I need this question to be answer asap

Answer 1

Since p(x) = r(x) - c(x), we can plug in r(x) and c(x) to find p(x).
p(x) = 11x - (6x + 20)
Make sure that your problem is subtracting all of c(x) and distribute the subtraction.
p(x) = 11x - 6x - 20
p(x) = 5x - 20
After simplifying, the final answer is D.

Answer 2

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.
