Answer:
The perimeter is just the sum of all four sides of the square.
36cm = Side 1 + Side 2 + Side 3 + side 4
Because it's a square, all the sides are the same length, so we can rewrite this as:
36cm = 4*Side
Side = 36cm/4 = 9cm
So to find the area, we multiply a length side, by a width side.
In this case (a square), we have:

Answer:
Step-by-step explanation:
x is common to both 15x and -12x; so is 3. Thus, the common factor is 3x.
Answer:
y=0
Step-by-step explanation:
Reorder the terms:
2 + -1(2 + y) = 3y
2 + (2 * -1 + y * -1) = 3y
2 + (-2 + -1y) = 3y
Combine like terms: 2 + -2 = 0
0 + -1y = 3y
-1y = 3y
Solving
-1y = 3y
Add '-3y' to each side of the equation.
-1y + -3y = 3y + -3y
Combine like terms: -1y + -3y = -4y
-4y = 3y + -3y
Combine like terms: 3y + -3y = 0
-4y = 0
Divide each side by '-4'.
y = 0
hope this helps
