Given the equation of a circle, (x - 6)^2 + (y + 7)^2 = 64, what would the center and radius of the circle be?

A: (6,-7); r = 64
B: (6,-7); r = 8
C: (-6, 7); r = 8
D: (6,-7); r = 32

B

Step-by-step explanation:

Set x-6 and y+7 equal to zero to find the center

So the center is (6,-7)

Take the square root of the right side to find the radius.

The answer is B

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

5y
