-512 is the answer because 512 is a negative solution in Integers math
5^2 + x^2=8^2
25+x^2=64
X=6.2
The domain is (1,3,5,7,9) and the range is (2,4,6,8,0)
There are 7 sides available.
The fundamental counting principal tells us to find the total number of combinations of independent items, multiply the number of choices from each one (choices x choices x....)
This means that drink x sides x sandwiches = 560. We know there are 16 sandwiches and 5 drinks. Let S be the number of sides:
15(6)(S) = 560
80S = 560
Divide both sides by 80:
80S = 560/80
S = 7
