Answer:

Step-by-step explanation:
Given formula:

To solve for 
In order to solve for
we will try to isolate
on one side of the equation.
Steps to isolate
.
1) Multiplying both sides by
to remove fractions.


2) Subtracting both sides by 


3) Subtracting both sides by 


Thus, we successfully isolated
on one side. The formula for
can be given as:
∴ 
The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>
The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Answer:
Center = (4, -5)
radius = 6
======================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
Rewrite the given equation into this form
(x-4)^2 + (y- (-5))^2 = 6^2
We can see that (h,k) = (4,-5) is the center and r = 6 is the radius.
Answer:
-12
Step-by-step explanation:
-36 divided by 3 = -12
