Answer 2

The simplified form of given expression is 22+r.

Explanation:

The given expression is

`20+(2+r)`

We need to find the simplified form of the given expression.

The given expression can be written as

`20+2+r`

In this expression r is variable and 20, 2 are constant terms.

Now, combine constant terms.

`(20+2)+r`

On further simplification we get

`(22)+r`

`22+r`

Therefore, the simplified form of given expression is 22+r.
