7 0

Answer:

x = - 5, - 6

Step-by-step explanation:

x^2 + 11x + 30 = 0

x^2 + 5x + 6x + 30 = 0

x ( x + 5 ) + 6 ( x + 5 ) = 0

( x + 6 ) ( x + 5 ) = 0

x + 6 = 0

x = - 6

x + 5 = 0

x = - 5

Find the center and radius of (x + 9)^2 + (y + 6)^2 = 9.
VARVARA [1.3K]
You can do this by comparing your equation to the general form of equation of a circle

( x - a)^2 + (y - b)^2 = r^2       where (a,b) is the centre and r = radius:-
(x  + 9)^2   (y + 6)^2 = 9 

so (a,b) = (-9,-6)  and r = 3

so the answer is B
