1/3(b + 4) = 1/2
1/3b + 4/3 = 1/2....multiply everything by common denominator of 6
2b + 8 = 3
2b = 3 - 8
2b = - 5
b = -5/2
or
1/3(b + 4) = 1/2...multiply both sides by 3
b + 4 = 3/2
b = 3/2 - 4
b = 3/2 - 8/2
b = -5/2

Answer: 90 degrees Celsius
Step-by-step explanation:
120-30 = 90
P = 2(L + W)
P = 36
36 = 2(L + W)
36/2 = L + W
18 = L + W....L = 18 - W
A = L * W
A = 65
L = 18 - W
65 = W(18 - W)
65 = 18W - W^2
W^2 - 18W + 65 = 0
(W - 13)(W - 5) = 0
W - 13 = 0 .....L = 18 - 13
W = 13 L = 5
W - 5 = 0 L = 18 - 5
W = 5 L = 13
Not exactly sure which (length or width)...but one is 13 ft and the other is 5 ft
