Answer 4

Hello, GG!
I'd like to see the work you've done towards obtaining you answer. Next time, OK?

\[If ~-1\le n+2\le 6\]our first job is to solve for n. Let's isolate n. We need to get rid of that +2. So: subtract 2 from all 3 terms: -1-2, n+2-2, and 6-2

What does doing this give you?

Answer 5

-6,-3, and 1?
