Question

I dont understand how to put questions together.​

Answer 1

D

Explanation:

You are subtracting two functions to get the profit, the formula is p(x)=r(x)-c(x). You know what two of those functions are equivalent to so plug it in to get

p(x)=11x-(6x+20)

to solve you must first get rid of the parentheses by distributing the negative.

p(x)=11x-6x-20

then, combine like terms (both x's)

p(x)=5x-20

That is your final answer.
