For this case we have the following expressions:
and 
Let:
(Integer m)
(Integer n)
By definition, an integer m is divisible by an integer n if the remainder of the division is 0. That is, there is an integer p such that: 
Rewriting the expression we have:

So:

We cancel similar terms:

We check:

Answer:
If they are divisible
Answer:
One: Median = 2
Two: Mean = 3.25
Step-by-step explanation:
One
Put the dots in order
1 1 1 2 2 3 3
There are seven groups altogether.
The middle one is a 2.
The median is 2.
Two
The mean is the average.
The average of the 4 groups is
1 3 6 3 = 13
The average is the sum of the dots.
13/4 = 3.25
You could say one person is at 1:5 and say they moved up and up
Answer:
perimeter = 4 
Step-by-step explanation:
Using the distance formula
AB = 
= 
= 
= 
The perimeter of a square is 4 times the length of one side.
So, perimeter = 4
