Explanation:
Here is an example of the distributive law in general terms.
a(b + c) = ab + ac
That is each term in the bracket is multiplied by a.
here there is only 1 value inside the bracket and so
2(19)=2xx19=382(19)=2×19=38

Explanation:
The easiest way to multiply
2(19)=2(20-1)2(19)=2(20−1)
Now use the distributive property, which states that
a(b+c)=ab+aca(b+c)=ab+ac
So, we see that
2(19)=2(20-1)=2xx20-2xx12(19)=2(20−1)=2×20−2×1
These are easier multiplication problems to do.
2(19)=2(20-1)=2xx20-2xx1=40-2=color(blue)382(19)=2(20−1)=2×20−2×1=40−2=38
