Answer:
100 feet would make the enclosure the longest
Step-by-step explanation:
The graph shows that at 100 feet the line is at its highest point.
Discrimination 100 the real answer is that and it will not make since at dirt but it is have a good day
Let f be the height of the fir trees
Let p be the height of the pine trees
We know from the problem that
f + p = 21 and 4f = 24 + p
rearrange the 2nd equation to get p = 4f - 24 and substitute into the other equation
so...
f + 4f - 24 = 21
5f - 24 = 21
5f = 45
f = 9 - height of the fir tree
substitute back into the 1st equation
9 + p = 21
p = 12 - height of the pine tree
