Answer:
Step-by-step explanation:
If we expand 4(3+x), we get (4*3)+(4*x).
Then we do 4*3 to get 12 and 4*x to get 4x
(3+3+3+3) is the same thing as 4*3, because we are adding 3 together 4 times. (3+3+3+3) gives us 12 as well, since they are the same thing.
(x+x+x+x) is the same thing because we are adding x together 4 times, which is the same thing as (4*x). (x+x+x+x) gives us 4x as well.
Hope this helps.
