Answer:
The circle is centered at (5, −7) and has a radius of 7.
Step-by-step explanation:
The standard form of the equation of a circle with center (a,b) and radius r is given as:

The given equation is

We rewrite to look like the stay form:

We now compare the two equations to get:
a=5, b=-7 and r=7.
Therefore the circle is centered at (5,-7) and has a radius of 7
Answer:
-12.
Step-by-step explanation:
-(-2а + 13) + (-9а - 2) - (-7а - 3)
= 2a - 13 - 9a - 2 + 7a + 3
= 9a - 9a - 13 + -2 + 3
= -12.
