Answer 1

D on e2021

Explanation:

Answer 2

The additive inverse is equal to
`-2a-b`

Explanation:

we know that

The additive inverse of a number is equal to its opposite ( the sum of a number and its additive inverse is equal to zero)

so

we have

`2a+b`

Multiply by -1

`-1(2a+b)=-2a-b`

therefore

The additive inverse is equal to
`-2a-b`
