There appears to be a typing error in the second equation.
Still the answer is (7,10) because it is the only ordered pair that works for the first equation.
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
Answer:
For me people called it PEMDAS, Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Becuase 1 is negative and one is postive
