Answer: 12x-6=14x-2
We move all terms to the left:
12x-6-(14x-2)=0
We get rid of parentheses
12x-14x+2-6=0
We add all the numbers together, and all the variables
-2x-4=0
We move all terms containing x to the left, all other terms to the right
-2x=4
x=4/-2
x=-2
Step-by-step explanation:
Answer: 200
Step-by-step explanation: to get the radius you divided by 2. bc there is only 2 sides , have a great day.
The steps are duplicated.Then, first I will write the steps in the right form:
19 = 5x - 1
20 = 5x
4 = x
Now, I will write the steps with the justification
19 = 5x - 1.... start
20 = 5x ..... Reason: addtion property of equality (you get this by adding +1 to both sides of the previous equality)
4 = x .... Reason: division property of equality (you get this by dividing by 5 both sides of the previous equality)

Area of a Circle Formula: A = πr²
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>r</em> = 6.5 m
<u>Step 2: Find Area</u>
- Substitute in variables [Area of a Circle Formula]: A = (3.14)(6.5 m)²
- Evaluate exponents: A = (3.14)(42.25 m²)
- Multiply: A = 132.732 m²
- Round: A ≈ 132.73 m²
