A rational number can be written as the ratio of one integer to another and can be represented by a repeating or terminating decimal.
we conclude that the center of the circle is the point (-5, 0).
<h3>How to find the center of the circle equation?</h3>
The equation of a circle with a center (a, b) and a radius R is given by:

Here we are given the equation:

Completing squares, we get:

Now we can add and subtract 25 to get:

Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).

Answer:
So, we conclude that Mark is right.
Step-by-step explanation:
If we have the following expression: 15 - (37 + 8) : 3.
We will first divide the value we get in parentheses and then subtract it.
Because sharing is an older mathematical operation than subtraction. Therefore, we get:

So, we conclude that Mark is right.
