Answer 1

C.
`-n - 2`

Explanation:

Given expression is
`3n+2(-2n-1)`

Now we need to simplify
`3n+2(-2n-1)` to create an equivalent expression then match with correct choice from the given choices:

A.
`-n + 2`

B.
`n + 2`

C.
`-n - 2`

D.
`n - 2`

`3n+2(-2n-1)`

`=3n+2(-2n-1)`

`=3n+-4n-2`

`=-n-2`

Hence correct choice is C.
`\bold{-n - 2}`
