Looking at this problem in terms of geometry makes it easier than trying to think of it algebraically.
If you want the largest possible x+y, it's equivalent to finding a rectangle with width x and length y that has the largest perimeter.
If you want the smallest possible x+y, it's equivalent to finding the rectangle with the smallest perimeter.
However, the area x*y must be constant and = 100.
We know that a square has the smallest perimeter to area ratio. This means that the smallest perimeter rectangle with area 100 is a square with side length 10. For this square, x+y = 20.
We also know that the further the rectangle stretches, the larger its perimeter to area ratio becomes. This means that a rectangle with side lengths 100 and 1 with an area of 100 has the largest perimeter. For this rectangle, x+y = 101.
So, the difference between the max and min values of x+y = 101 - 20 = 81.
Answer:
the slope of a line is the rise over run from plot to plot.
a. 3/5
b. 3/4
c. 2
Step-by-step explanation:
i hope this helps :)
B. 54
Because 54+13=67
67+54=121
Answer:
2n - 3
Step-by-step explanation:
(n-2) + (n-1) = 2n - 3
This is not the answer, but I want to tell you that I can't see what the problem says. I would help you, but I can't.
