Answer:
![VW = 33](https://tex.z-dn.net/?f=VW%20%3D%2033)
Step-by-step explanation:
<em>See attachment for complete question</em>
Given
![VY = 4x - 1](https://tex.z-dn.net/?f=VY%20%3D%204x%20-%201)
![VW = 5x + 3](https://tex.z-dn.net/?f=VW%20%3D%205x%20%2B%203)
![Perimeter = 112](https://tex.z-dn.net/?f=Perimeter%20%3D%20112)
Required
Determine the length of VW
Perimeter is calculated as:
![Perimeter = 2 * (Width + Length)](https://tex.z-dn.net/?f=Perimeter%20%3D%202%20%2A%20%28Width%20%2B%20Length%29)
This gives:
![Perimeter = 2 * (VW + VY)](https://tex.z-dn.net/?f=Perimeter%20%3D%202%20%2A%20%28VW%20%2B%20VY%29)
Substitute values for VW, VY and Perimeter
![112 = 2 * (4x - 1 + 5x + 3)](https://tex.z-dn.net/?f=112%20%3D%20%202%20%2A%20%284x%20-%201%20%2B%205x%20%2B%203%29)

![112 = 2 * (4x + 5x -1 +3)](https://tex.z-dn.net/?f=112%20%3D%202%20%2A%20%284x%20%2B%205x%20-1%20%2B3%29)
![112 = 2 * (9x +2)](https://tex.z-dn.net/?f=112%20%3D%202%20%2A%20%289x%20%2B2%29)
Divide through by 2
![56 = 9x + 2](https://tex.z-dn.net/?f=56%20%3D%209x%20%2B%202)
Collect Like Terms
![9x = 56 - 2](https://tex.z-dn.net/?f=9x%20%3D%2056%20-%202)
![9x = 54](https://tex.z-dn.net/?f=9x%20%3D%2054)
![x = 54/9](https://tex.z-dn.net/?f=x%20%3D%2054%2F9)
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
Substitute 6 for x in ![VW = 5x + 3](https://tex.z-dn.net/?f=VW%20%3D%205x%20%2B%203)
![VW = 5 * 6 + 3](https://tex.z-dn.net/?f=VW%20%3D%205%20%2A%206%20%2B%203)
![VW = 30 + 3](https://tex.z-dn.net/?f=VW%20%3D%2030%20%2B%203)
![VW = 33](https://tex.z-dn.net/?f=VW%20%3D%2033)
