To solve the equation 2x - 6 = 14, first
Anna [14]

2x - 6 = 14

Add 6 to both sides to isolate the x

2x = 20

Divide 2 to both sides since x is multipled to x

x = 10

To check your work plug 10 into the equation

2(10) -6 = 14

20 - 6 = 14

14 = 14

and it works

1. A rancher wants to build a rectangular pen, using one side of her barn for one side of the pen, and using 200m of fencing for
bezimeni [28]

Answer:

100m by 50m.

Step-by-step explanation:

Let the dimension of the rectangular pen be x and y

Area, A(x,y)=xy

Let the side opposite her barn = x

Since she wants to fence only three side

Perimeter = x+2y

Length of Fencing Available = 200m

Therefore: x+2y=200 \implies x=200-2y

We want to maximize the area of the pen, A(x,y).

Substituting x=200-2y into A(x,y)=xy

A(y)=y(200-2y)\\A(y)=200y-2y^2

To maximize A(y), we find its derivative and solve for the critical points.

A'(y)=200-4y\\$Setting $A'(y)=0\\200-4y=0\\200=4y\\y=50

To ensure that this is a maximum, we use the second derivative test.

A''(y)=-4

This is negative and thus, y=50 is a maximum point.

Recall:

x=200-2y

x=200-2(50)

x=200-100

x=100m

Therefore, the dimensions of the pen that has the largest area are 100m by 50m.
