Answer:

Step-by-step explanation:
s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
3^3 the answer is the first one with the exponent 3
x = -3
So to figure this out we can readjust the equation to make it easier to solve
is equal to 
From here we can just subtract 9 from both sides and we get our answer!
