Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. If a number is terminating or repeating, it must be rational if a decimal is both non terminating and non repeating, the number is irrational.
So yes.
Answer:
5n^2 - 3n - 8
Step-by-step explanation:
4n.5n - 4n.8 + 4.5n - 4.8
= 20n^2 - 32n + 20n - 32
= 20n^2 - 12n - 32
= 4 ( 5n^2 - 3n - 8 )
= 5n^2 - 3n - 8 [ answer ]
All work shown, I hope that this works!

I found this is may help but I don't know for sure.
Answer:
y = -3
Step-by-step explanation:
2 - 4(y + 1) = 2y + 16
2 - 4y - 4 = 2y + 16
2 - 4 = 6y + 16
- 2 = 6y + 16
- 18 = 6y
-3 = y
