Answer:
Step-by-step explanation:
Let x = length of fenced side parallel to the side that borders the river
y = length of each of the other two fenced sides
Then, x + 2y = 4500
<=> x = 4500- 2y
Area = xy = y(4500-2y)
= + 4500y
The graph of the area function is a parabola opening downward.
The maximum area occurs when y = -4500/[2(-2)] = 1125
x = 4500-2y = 2250
To maximize the area, the fenced side parallel to the pone be 2250 feet long, while each of the other two fenced sides should be 1125 feet long.

Answer:
Step-by-step explanation:
8z, 12y, 7.7 are separate terms
z and y are variables
8 and 12 are coefficients
7.7 is the constant
The length of a rectangle is 12 inches more than its width. What is the width of the rectangle if the perimeter is 42 inches?
x best represents .
x + 12 best represents
X=2 is the answer hope it helps
