BEST ANSWER GETS BRAINLIEST!! PLEASE HELP

Answer 1

Part A: 
3(10m +5)
3m + 15 + 27m

Part B:
3m + 15 + 27m = 3(m + 5 + 9m) ....factor
using distributive property

Part C:
let m = 1

3(10m +5) 
= 3[(10(1)+5]
=3(10+5)
=3(15)
=45

3(m + 5 + 9m)
= 3[(1+5 + 9(1)]
=3(1+5+9)
=3(15)
=45

both are equilvalent
