The answer is or is equivalent to -x=3
10p - 5c + 2p + 8c
= 10p + 2p - 5c + 8c
= (10+2)p + (-5+8)c
= 12p + (8-5)c
= 12p + 3c
Answer:6
Step-by-step explanation:
from Pythagoras principle we get
x=√(10^2-8^2)
x=√(10x10-8x8)
x=√(100-64)
x=√(36)
x=6
You can reduce the expression by cancelling out common factor
