Answer:
5(10+2)
Explanation:

Because multiplication is commutative the above ,can be rewritten as

We now choose any two numbers (say 2 and10) that sum up to 12, put it in bracket and multiply by 5.
This implies that,

using distributive property, we obtain
5(10)+5(2)
=50+10
=60
We can see that the product of 5 and 12 equals 5(10+2)
Hence the distributive property is 5(10+2)
