For the value of p as 4, the given expression 3(4+n) will be equivalent to 3(n+p).
The given expression is [tex]3(4+n)[/tex].
It is required to find the value of p such that the given expression is equivalent to the expression [tex]3(n+p)[/tex].
Now, the given expression can be written as,
[tex]3(4+n)=3(n+4)[/tex] because addition follows commutative law.
Now, compare the given expressions to get the value of p as,
[tex]3(n+4)=3(n+p)\\n+4=n+p\\4=p[/tex]
Therefore, for the value of p as 4, the given expressions 3(4+n) will be equivalent to 3(n+p).
