Question

Can someone help me please? and probably explain it if you can.

Answer 1

Answer:

6x-15

Step-by-step explanation:

P(x) = r(x) - c(x)

      = 10x - (4x+15)

 Distribute the minus sign

    = 10x-4x -15

 Combine like terms

    = 6x-15

Answer 2

Hey there! :)

Answer:

p(x) = 6x - 15

Step-by-step explanation:

If p(x) = r(x) - c(x), subtract the two equations. Therefore:

p(x) = 10x - (4x + 15)

p(x) = 10x - 4x - 15

Combine like terms and simplify:

p(x) = 6x - 15
