Completing the squares, the correct statements regarding the equation of the circle are given by:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
In this problem, the equation is given by:
x² + y² - 2x - 8 = 0.
Completing the squares:
(x - 1)² + y² = 8 + 1²
(x - 1)² + y² = 9.
Hence the center is (1,0), the radius is 3, and the correct statements are:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Answer: Reliability
Explanation: Reliability is the term that is used in the field of the tool which defines the consistency of the variables and the results. It assures that the readings of the valuers that are obtained can be repeated in future experiments or study. It is also known as the dependability.
Other options are incorrect because trustworthiness and credibility are referred as the validity of the collected values and triangulation is known for tracking.Thus, the correct option is reliability
Answer:
It would stay the same.
Step-by-step explanation:
You only switch it if you are dividing by a negative.
The four consecutive odd integers are x, x+2, x+4, x+6
x+x+2+x+4+x+6=216
4x+12=216
4x=204
x=51
they are 51, 53, 55, 57
