Given: A= 52ft² and l= 2w-5
know that formula for A= lw, substitute for what you know and solve for w
52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft
now input that in the equation for length and solve for l:
l=2w-5=2(6.5)-5=8
so the length is 8 ft

Answer:
Choice B
Step-by-step explanation:
Choice B is not a proportional relationship because it is not in the form of Y = KX.
First, you must convert the equation, X - Y = 2 to Y = MX + B by subtracting X to the right side to get -Y = -X +2. Then divide each side by -1 to get a positive Y value. Then you are left with Y = X - 2, which is not in the form of Y=KX.
