7 0

To solve this problem,all you can do is simplify. First use the distributive property:

-1.5 * 4= -6
-1.5* n= -1.5n
now you should have this:

-6-1.5n+2.8

Now combine like terms:

-6+2.8= -3.2

Now you have simplified it as much as you can:

-3.2-1.5n is your answer.

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:

I personally don't know how to answer.. but it wants you to write the answer in function notation.

For example ^: 2^7: 2x2x2x2x2x2x2
