A = L * W
A = 44
L = 2W - 3
44 = W(2W - 3)
44 = 2W^2 - 3W
-2W^2 + 3W + 44 = 0
(-2W + 11)(W + 4) = 0
W + 4 = 0
W = -4......not this one because it is negative
-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5 <=== width is 5.5 yds
L = 2W - 3
L = 2(5.5) - 3
L = 11 - 3
L = 8 <=== length is 8 yds

Answer:
It's the left graph, y = f(x)
Step-by-step explanation:
If you find the x-intercepts, you'd solve (2-3x)/x = 0. This means you'd really solve 2-3x=0, which gives you x=3/2.
So the graph must have an x-intercept at (1.5, 0). Only f(x) has that.
26 / 2/3 = 39
