10p - 5c + 2p + 8c
= 10p + 2p - 5c + 8c
= (10+2)p + (-5+8)c
= 12p + (8-5)c
= 12p + 3c
Answer:
2x(squared)-8x
Step-by-step explanation:
when you distribute the 2x to x you get 2x squared and when 2x is distributed to -4 you get -8x and together you get 2x squared minus 8. :)
Formula for circumference: 2πr
r=2x+1
C=2π(2x+1)
distribute
C=4πx+2π
