Four Tangent circles are centered on the x-axis. The radius of circle A is twice the radius of circle O. The radius of circle C is four times the radius of circle O. All circles have integer radii and the point (63,16) is on the circle. What is the equation of circle A?

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
