Answer:

Question 8.) Choice d.) 4 + x + 6x = 4 + 7x

Question 9.) Choice b.) 18 - 15 + 4n + 5n simplifies to 9n + 3

Step-by-step explanation:

For the first question, like terms are terms that have the same variables, and not necessarily the same coefficient numbers.

first problem, x + y + xy all have unique terms. x is different from y and is different from xy

so it cannot be A.

Choice d. has like terms x and 6x so 4 + x + 6x can simplify to 4 + 7x

Choice b.) 18 - 15 + 4n + 5n simplifies to 9n + 3

Show work, please!

Let's try this.
First, we have the absolute value of -4(-2)-8, or the absolute value of 8-8, so 0.
Let's forget about that, now. It's 0, it adds no value. Let's not worry about it.
For the next, we see the absolute value of -1-(-2)^2
Or:
-1-4, or -5.
Next is 2(-2)^2, or 2(4) = 8.
Therefore, we have -5+8 =3.
If you see any errors, let me know.
Otherwise, I hope this helps!
