Answer:
There is know answer because it doesn't give the number of friends Jason has.
I need more description of solve it
54m=P 170=A
x+y=54, y=54-x
x*y=170, y=170/x
54-x=170/x
54x-x^2-170=0
x^2-54x+170=0
x= (54(+/-)root2916-680)/2
x=27(+/-)root559
x+y=3.35+50.65=54
x*y=3.35*50.65=170m
Dimensions are 3.35m and 50.65m
The domain is all of the x values which are the first number in each set of parentheses and the range is all of the y values therefore domain = {2, 1, 5, 3} and range= {2, -7, 3, 0}
The geometric means between 12 and 9 is 10.3923
