p(x) = r(x) - c(x)
p(x) = 10x - (4x+15)
10x - 4x = 6x
The answer is C 6x - 15 because the negative is distributed into the positive 15 to make it a negative.
<span>15 sides is the right answer
hope it helps

Simplify <span>8(7x – 1) + 4(x + 5)
Step 1: Distribute
56x - 8 + 4x + 20
Step 2: Combine like terms
60x + 12
60x + 12 is your final answer</span>
6+9=15
15 Divided by 2=7.5
Therefore your answer will be 7.5
