Let's find the expressions for the length and width of the rectangle. The length (which we will call <em>l</em>) is 2 units less than some undefined number, thus we will use the variable <em>x</em>:
l = x - 2
The width is 4 more than this length:
w = l + 4 = (x - 2) + 4 = x + 2
Now, given that we have the length and width and are looking for the area, we need to multiply these expressions together.
One way to write this would simply be (x + 2)(x - 2). If we wanted to find a different way of writing the area, we could use FOIL to find all terms and get x^2 - 4.
Answer:
259
Step-by-step explanation:
You could set up an equation that looks like:

Then solve for 
1. subtract 92 from 251

2. add 100 to both sides

Over 5 weeks 20 reduction in waste removed.
Therefore 4 per week.
Therefore gradient -4w.
-4 x 5 + c = 60
-20 + c = 60
c = 80
dumpsters removed = d
weeks = w
d = 80 - 4w
