Suppose x is any positive number why is circle 1 similar to circle circle 1: center (0,0) and radius 2x circle 2: center (0,0) and radius 10x a circle 2 is a dilation of circle 1 with a scale factor of 5 b circle 2 is a dilation of circle 1 with a scale factor of 8 c circle and circle 2 have equal areas d both circles are centered at the origin

First choice "A circle 2 is a dilation of circle 1 with a scale factor of 5" is correct.

Step-by-step explanation:

We have been given information about two circles as given below:

circle 1: center (0,0) and radius 2x

circle 2: center (0,0) and radius 10x .

Now we need to find about why is circle 1 similar to circle where x is any positive number.

We know that all circles are similar. So after dilation it doesn't affect their similarities.

10x can be obtained from 2x, by multiplying  2x with 5.

So the first choice "A circle 2 is a dilation of circle 1 with a scale factor of 5" is correct.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

the first one, all those points on the line just make a strait line.
