The equation for a circle is as followed:

where the center of the circle is at (h,k) and the radius of the circle is r.
We are given (h,k) and need to find the radius. To do so, we can use the distance formula to find the distance from the center to the point on the circle:

Plug in the two points:



If the distance from the center to the edge of the circle is the square root of 117, then r^2 = 117.
The answer is:
Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
Step-by-step explanation:
measure all the sides then multiply you will get the answer
Answer:
x > 9.
Step-by-step explanation:
Here it is just simplifying the inequality.
6 - 2/3x < x - 9
Add 2/3x to both sides.
6 < 5/3x - 9
Add 9 to both sides.
15 < 5/3x
Multiply by 3/5.
9 < x
Flip it.
x > 9.
