Answer:
The simplified form of given expression is 22+r.
Step-by-step explanation:
The given expression is
[tex]20+(2+r)[/tex]
We need to find the simplified form of the given expression.
The given expression can be written as
[tex]20+2+r[/tex]
In this expression r is variable and 20, 2 are constant terms.
Now, combine constant terms.
[tex](20+2)+r[/tex]
On further simplification we get
[tex](22)+r[/tex]
[tex]22+r[/tex]
Therefore, the simplified form of given expression is 22+r.
