Answer:
(-7, 4) and 7
Step-by-step explanation:
The standard equation of a circle is expressed as (x - a)^2 + (y - b )^2 = r^2
Where the center is the point (a, b) and the radius is r
Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)
The square root of the radius gives you the value for r

Answer is........... x= 9168
Step-by-step explanation:
A = 1
b = 11
c = 30
(quadratic formula)
but what are you asking?
4(1)(30)
= 120
(-38) - 11 - 22
-(38-11-22) = -(38 +11 + 22)
-(38 + 11 + 22) = -(71)
The answer is -71
