**Answer:**

The distributive property allows you multiply a sum in parenthesis by multiplying each addend separately, then add the products.

**Step-by-step explanation:**

How to use the distributive law example.

2(x+4) = 16

To use the distributive law in this example multiply 3 by all terms in the parenthesis. Multiply 2 and x, then 2 and 4 to open the parenthesis.

2x+8=16

That is how you use the distributive law.

To continue solving, subtract 8 from both sides.

2x+8-8=16-8

2x=8

Divide 2 from both sides.

2x/2=8/2

x=4

Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer

You divide and get 3/7 meters per second
