Answer 1

Answer:

2,6 12,k

Step-by-step explanation:

2×12=6k

24 =6k

k= 4

Answer 2

Step-by-step explanation:

Terms in this set (15)

Circle

The set of all points in a plane that are the same distance from a given point called the center.

Represented using standard form, (x-h)^2+(y-k)^2=r^2

h is the x coordinate, k is the y coordinate, r is the radius

General form of a circle and converting this into standard form

General form is x^2+y^2=Ax+By+C= 0

You get this by multiplying out both of the terms that are squared. The coordinate of the center is (-1/2A, -1/2B).
