If n is odd then its cube is also odd because odd times odd is odd. When we add 5, an odd number, we get an even number.
If n is even, its cube is also even so adding an odd number makes the sum odd. So if the expression is odd, n must be even.

Answer:
(2,-7)
Step-by-step explanation:
Plug in the numbers to test and see if it gives you -17 and -8.
Option 1. 2(-4)+3(2)
= -8+6 = -2. Not it.
Option 2. 2(2)+3(-7)
4 - 21 = -17 Works. Try the second equation to make sure.
3(2)+2(-7)
6-14 = -8. Works.
(2,-7) is the answer.
Theoretically =theory is potentially done, experimental is experiment XD XD. They both have to do with probability
