We are given the following expression
[tex]3p+5p+p[/tex]Let us simplify the expression.
Notice that each term has the same variable (p) so we can simply add the coefficients of terms together.
[tex]\begin{gathered} 3p+5p+p \\ \mleft(3+5+1\mright)p \\ (9)p \\ 9p \end{gathered}[/tex]Therefore, the simplified expression is 9p
