how do i subtract and simplify: (11x2 + 7) – (6x2 + 3x – 3)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

the aswere is the one with all 8's and the second one is with the 10,8 and 6
