Important information:
- The given statement is "multiply 3 by the sum of m and p".
We need to find the algebraic expressions for the given statement.
Algebraic expressions:
"+" sign represents sum. So, the sum of m and p is [tex](m+p)[/tex].
Multiply 3 by the sum of m and p. So,
[tex]3\times (m+p)[/tex]
