Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is
, where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
4x°=75-x° this might be wrong but I’m sure
Let "what" and "what" be A and B
Put this in an algebraic equation
A * B = 21
A + B = -22
A must = -21 and B must = -1 , this is because two negatives multiply to make a positive
A + B = -22 , -21 +-1 = -22
