Answer:
Distributive
Step-by-step explanation:
3(x + 5) = 7x - 13   given
3x + 15 = 7x - 13   distribute
- 3x -3x   Subtraction property of equality
15= 7x - 13
+13 +13    Addition property of equality
28 = 7x   
7 7   division property of equality
4=x   simplify
x=4

Answer:
The circumference of the circle is 6 cm (approximately).
Step-by-step explanation:
Given:
Area of the circle = 1/4π²
Now, to get the circumference of the circle we need the radius.
So, finding the radius by putting the formula of area:
Area = 
 =
 =  
 
dividing π by both sides:


using square root on both the sides:

So, the radius is 
Now, putting the formula of circumference:

                               =
                               =
putting the value of π =3.14
                               =
                               =
                               =
Circumference = 5.56 cm
Therefore, the circumference of the circle is 6 cm (approximately).
