Easy, make it easy to do mentally than add the remaining

Answer:

12 + 20 = 4*3 + 4*5 = 4*(3 + 5)  

Step-by-step explanation:

Distributive property states

a*(b + c) = a*b + a*c  

Look if you know that 12 = 4*3 and 20 = 4*5

You can write it as

12 + 20 = 4*3 + 4*5 = 4*(3 + 5)  

That would be it in distributive property
