The side length of a square is: x + 1
Write the simplified expression for the square's perimeter

Basic fact:

all sides of a square are equal

Step-by-step explanation:

1 side is x+1 so all sides are x+1

there are 4 sides so times everything by 4

4(x+1) which is 4x+4

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
