Answer:
distributive propriety
Explanation:
Step 1 was distributive propriety because
We distributed the multiplication between 14 and (x+5) over the addition x+5
If we have 14 multiply by a number will just do that. (e.g. 14*3= 42)
If we have 14 multiply by a number written as the sum of others we need to distribute to each part. (e.g. 14*(1+2) = 14*1 +14*2 = 14+28 = 42)
