Answer:
The simplified form of given expression is 22+r.
Step-by-step 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.
