Answer:
the answer is 0
Step-by-step explanation:
Answer:
-3/2 < x < 5......................
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
Solve for w and l by using the system of equations.
2l=-2w+228
l=w+42
Substitute w+42 for l in the first equation.
2(w+42)=-2w+228
2w+84=-2w+228
4w=144
w=36
Now substitute 36 for w in any equation to get l=78.
To graph the equations, first make them equal l.
l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.
