If (5, 4) and (7, 2) are the endpoints of a diameter of a circle, what is the equation of the circle? A)(x − 6)2 + (y + 3)2 = 2 B)(x − 6)2 + (y − 3)2 = 2 C)(x + 6)2 + (y +3)2 = 8 D)(x + 6)2 + (y − 3)2 = 8

B

Step-by-step explanation:

(5+7)/2 = 6

(4+2)/2 = 3

center = (6, 3)

diameter = √(5-7)²+(4-2)² = √8 = 2√2

radius is half diameter = √2

Equation for circle is (x-6)²+(y-3)²=2

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
