Question

Use the distributive property to simplify the algebraic expression. (n + t)r

Answer 1

When it says to use distributive property, it means that you are going to "distribute" a variable and/or number to others.
To solve this (n+t)r .... then you would multiply "r" to "n" and then to "t".
It would end up looking like this... nr+tr .
This is your final answer because nothing else can be done to it. :)
I hope I helped you understand.
