40 flights, you could use rates in this situation.
15 min*4=60 min=1 hr
10:15 multiply each side by 4
40 flights:60 minutes
Answer:
60
Step-by-step explanation:
x²=36×(64+36)
x=√3600
x=60
You can only cut down a integer number of trees. So you might look at a few integer values for x. As x get large the –x4 term dominates the expression for big losses. x = 0 is easy P(x) = -6. Without cutting any trees you have lost money Put x = 1 and you get for the terms in order -1 + 1 + 7 -1 -6 = 0. So P(x) crosses zero just before you cut the first tree. So you make a profit on only 1 tree. However when x=10 you are back into no profit. So compute a few values for x = 1,2,3,4,5,6,7,8,9.
