Answer:
17
Step-by-step explanation:
The two integers could be -1 and 18.
18 + -1 = 17
Any other combination of integers that have a product of -18 would have a smaller sum.
X=5 because 4x5=20 and 20-4=16
A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a
so 4 sqrt 7 is the length of each side
