Answer 7

for #1 i got 1k

Answer 8

1 is right,
as a note, "1k" is the same as "k" since anything times 1 is the same value

Answer 9

okay what about the others

Answer 10

3 is fine, but 2 is wrong

Answer 11

okay so what did i do on two that was wrong

Answer 12

12r-8-12
unless the question is different than as shown, your answer 2 was absolutely completely wrong

Answer 13

you just add up like terms
or we can group them up

12n +(-8-12)

Answer 14

we'll notice that there is no other term with the variable n so we can leave 12n alone

the only like terms we see are -8 and -12

adding those together and you get?

Answer 15

-20?

Answer 16

yea so add that together with 12n
the complete answer is?

Answer 17

12n+20
