Answer:
7x-2 = 12x-22
-7x
-2=5x-22
+22
20=5x
÷5
x=4
KL is 7x-2, so substitute the value of x.
7 x 4 - 2 = 26
KL = 26

Current worlds population is 7.6 billion (7,600,000,000), so Japan’s population is equal to 1.67 % of the world’s population.
Hi, Ptaverez1! :)
First we must length of an individual square; This can be achieved by using the formula for the area of a square:


Lets input the information we already know:

Take square root.


The length of an individual square tile is
6.5 ft.
Since they're are 9 tiles and the porch in a square, I can conclude that the measurements for the porch are 3 tiles by 3 tiles (as 3*3=9; using the formula for the area of a square.)
Since the length of the porch is 3 tiles, we must multiply the individual tiles piece length by 3:


The formula for the perimeter of a square is:


Lets input the information we know:


The perimeter of the porch is 78 feet²

Step-by-step explanation:
3+x=x²+3x
Simply the equations.
= x+3=x²+3x
Subtract x²+3x from both sides.
x+3−(x²+3x)=x2+3x−(x²+3x)
−x2−2x+3=0
Factor left side of equation.
(−x+1)(x+3)=0
−x+1=0 or x+3=0
Answer:
x=1 or x=−3
