Is either x = 7 or x = 9 a solution to 2.2 192 A. x = 7 is a solution, but x = 9 is not. B. Neither is a solution. C. x = 9 is a solution but x = 7 is not D. They are both solutions​

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

equal to

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.
