If the pencil markings are correct, LM=NP.
This means that both lines should be the same length (you've marked them as congruent). Therefore, you can set the two equations equal to one another.
3x=5x-14
You should get a solution of x=7. If you have trouble with that, comment. I was lazy and did it with my graphing calculator, but I can show you how to do it algebraically.

From the drawing, assuming your congruency markings are correct, K is the midpoint of LM. Therefore, LK will be half the length of LM.
As LM looks like it equals 3x, LK would be 3x/2. In the above step, I found that x=7. Plug x unto the equation 3x/2 to get 21/2, which is your final answer.

A circle is a set of all points that are the same distance from one given point. Find an wxample that cotradicts this definition

eduard

Answer:

Part A

The given definition of a circle is the set of all points that are the same distance from one given point

One example that contradicts the definition, is the set of all points in a three dimensional plane which are equidistant from, a point, which is the definition of a sphere

Part B

The definition of a circle can be modified to include the location of the points <em>on the same plane</em>, from which we therefore have;

<em>A circle is a set of all points on a plane that are the same distance from one given point</em>
