Answer: b = p - a -c
Step-by-step explanation:
p= a + b + c Solving for b means getting b on one side by itself.
p = a + b + c To solve for b first subtract a from both sides to get,
-b -b
p - a = b + c Now subtract c from both sides to get
-c -c
p - a - c = b
b = p - a -c
Answer:
b = P - a - c
Step-by-step explanation:
Perimeter P = a + b + c
find b
P - a - c = b
b = P - a - c
