Answer :
hello!
==============================================================
The distributive property states that:-
[tex]\bigstar{\underline{\boxed{\pmb{a(b+c)=ab+ac}}}[/tex]
Simplify:-
[tex]\bigstar{\boxed{\pmb{5(7h+3m)}}}[/tex]
[tex]\longmapsto\sf{(5~times~7h)+)5*3m)[/tex]
[tex]\longmapsto\sf{35h*15m}[/tex]
===============================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
