-2 is the answer when i figured out the problem
This system can be a bit tricky unless you write it out:
(2n + 2)(2n - 2) ~ First you have to take one variable and multiply it to each of the other two variables, like:
2n * 2n ~ And:
2n * -2 ~ This gives you:
4n^2 - 4n
Now we do this with the other:
2 * 2n
2 * -2
4n - 4
Now we combine them both while adding like terms:
4n^2 - 4
Therefore your answer is: A. 4n^2 - 4
(This is due to how when having the positive 4n subtracted by the negative it cancels it out. Leaving us with the remaining two terms left.)
I hope this helps, have a great rest of your day! ^ ^

Answer:
<h2>Basic numbers</h2><h3>Numbers up to nine should always be written in words, anything higher than nine can be written in numerals. Alternatively, some guides suggest that if you can write the number in two words or fewer then use words rather than number.</h3>

There are 5 data values.
Mean = (22 + 37 + 49 + 15 + 83) / 5 = 41.2
Essential h(40) is the equivalent of when y=40. Together, when y=40 x=1700, kind of like a coordinate pair (40, 1700).
