The equation of the circle x² +y² – 8x – 6y + 21 = 0 is equal to the equation (x + 4)² + (y − 3)² = 2². Then the correct option is C.
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² – 8x – 6y + 21 = 0
The equation can be written as
x² – 8x + 16 + y² – 6y + 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

Answer:
x=25
Step-by-step explanation:
2x=5*10
x=50/2
x=25
D) The stocks yielded $973.40 more in profits than the bonds.
Given two similar figures, the ratio of any two corresponding sides measures with the equal in square to the ratio of any two corresponding area measure. Let x be the separation of the two long parallel sides in the larger patio.
x²/12.5<span>² = 360/250
x</span>/12.5<span> = 6/5
x</span><span> = (6*12.5)/5
x</span><span> = 75/5 = 15
That is the corresponding distance on the new patio.</span>
He deposited $29, so a $29 dollar difference
