I have no idea what the "5-D Process" is. However:
2W = L-1
2W + 2L = 74
Add 1 to both sides of the first equation to isolate L.
2W+1 = L
Now substitute this value for L in the second equation:
2W + 2(2W + 1) = 74
2W + 4W + 2 = 74
6W + 2 = 74
6W = 72
W = 72/6 = 12
L = 2W + 1 [from above] = 2(12) + 1 = 24 + 1 = 25.
25 is one more than twice the width. 25 + 25 + 12 + 12 = 50 + 24 = 74

Step-by-step explanation:
The interval notation of the graph is [-1, 3).
The -1 has a closed circle, which means that -1 as an endpoint is included.
3 has an open circle to it, which implies that it is not included as an endpoint.
The interval can also be expressed as:
-1 ≤ x < 3
