Answer:

C

Step-by-step explanation:

You can tell C is the right answer because one of the inequalities is a vertical line at y=3, which rules out all the other answers. However, if you continue to look at the 2nd inequality, you find the equation is x + y > 2, because the slope is -1 and the y-int is 2.

A farmer has 324 feet of fencing to make three identical adjacent rectangular pens, as shown in the picture. What dimensions of
egoroff_w [7]

The dimensions of each pen that will maximize the total enclosed area would be as; Length 81 feet; Width 81 feet.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let the Dimension of each pen

Length = x

Width = y

Area = xy

Perimeter equation

2(x + y) = 324

 x + y = 162

Substituting the perimeter equation

Area = x(162 - x)

Area = -x^2 + 162x

If the zeros of the quadratic are 0 and 162, then the median will be at where the maximum area occurs.

162/ 2

= 81

Hence, The dimensions of each pen that will maximize the total enclosed area would be as; Length 81 feet; Width 81 feet.
