Answer:
9
Step-by-step explanation:
The equation is simply 8s where s is the length of a side. There are 8 sides. You are just adding the length of all 8 sides together to get the perimeter.
P-4(p-2(3-p))=12 remove the parentheses
P-4(p-6+2p)=12 collect like terms
P-4(3p-6)=12 remove the parentheses
P-12p+24=12 collect like terms
-11p+24=12 move the constant to the right
-11p=12-24 calculate
-11p=-12 divide both sides
P=12/11
Alternative form
P=1 1/11
