Triangle GED and triangle DEH are similar triangles with a common side length DE
The value of x is 24
<h3>How to calculate the value of x</h3>
To calculate x, we make use of the following equivalent ratio
Substitute known values
Express the ratio as fraction
Evaluate the quotient
Multiply both sides by 35
Subtract 4 from both sides
Hence, the value of x is 24

Answer: -3
Explanation:
since its parallel that means its on the x-axis. So, y=0.
put y=0 in the equation
3(0)-3x=12
-3x=12
x=12/-4
x=-3
The positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.
<h3>What is the circumference of the circle?</h3>
The circumference of the circle may be defined as the total stretch of the boundary of the circle. The formula for calculating the circumference of the circle is as follows:
where, C = circumference of the circle.
π = the constant pie.
r = radius of the circle.
According to the question,
The circumference of the circle A = 2π (r+1).
The circumference of the circle B = 2π (r+2).
∴The positive difference between the circumference of circle B and the circumference of circle A is as follows:
2π (r+2) - 2π (r+1) = 1.
Therefore, the positive difference between the circumference of circle B and the circumference of circle A is 1. Thus, the correct option for this question is A.
