Two figures are similar are one of them can be obtained from the other with some transformations (reflections, translations, rotations, dilations) <span> . The circle is defined by only one length - the radius.

To prove that all circles are similar you would use the sequence of similarity translation and dilation.
A translation, followed by a dilation with scale factor r2/r1 will map one circle onto the other, thus proving that the circles are similar.
Answer:
-15
Step-by-step explanation:
First you want to make the -9 into positive because 2 negitives next to eachother equals a positve and them you add together to get 5=x. Lastly you times 5 by -3 to get -15
Yes your answers are correct
