How do I solve this problem?

18

Step-by-step explanation:

Let FG Be x

As they are similar to each other

EJ/JH= EF/FG

Or, 12/24= 6/x

Therefore, x= 12

Now,

EG= EF+ FG

= 6+ 12

= 18

Hope it helped ya :)

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
