Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>

1)

</h2>
=> 72.0
2)
<h2>

</h2>
=> 616.0
If we add the two numbers we get....
=> 72.0 + 616.0
=> 688.0
<em><u>Ans.</u></em>

HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
Answer:
The answer is "2"
Step-by-step explanation:
When we check the points where the x is -2
by calculating the "y-value":
It is 2, right?
it implies that 
that's why the final answer is "2"
