Answer:
8/5 is the answer, I know this because when I used the answer the other dude gave me I got it wrong so trust me it is 8/5
One expression you can do, is to simply simplify the expression,
We can deistribute the 3
6n+9+9
You can then simplify further:
6n+18
Once we have the simplified expression, you can then expnd it in different ways for example:
3(2n+6)
Hope these helped!

Answer:
pairs of numbers is 3,-3
Step-by-step explanation:
The computation is shown below:
Let us assume a and b are the pairs of the numbers whose difference is 6
i.e.
a - b = 6
a = 6 + b
So
f = ab
f = (6 + b)b is minimum
Now
d ÷ db (6+ b)b = 0
(6+ b) + b = 0
2b = -6
b = -3
Now
a = 6 + b
= 3
So pairs of numbers is 3,-3
