Answer:

x= -3

Step-by-step explanation:

Move The Terms:

8x -2x =3 = -15

Divide both sides of the equation by 6:

x = -3

John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length,
kati45 [8]
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.

P = 28 ft.
Length = x
Width = (1/2)x + 2

So now we can plug in the little equations of length and width into a perimeter formula:
 2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8

To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6

So, the length is 8 feet and the width is 6 feet.

5/6 of 54 is 45, so you would need to subtract 45 from 54, which is 9. 
I hope you find this useful, and, if so, please mark as brainliest :P
Good luck!
