Given the scale drawing of a one bedroom apartment what is the actual perimeter of the study

Solve |x| > -9 a) {x|x< -9 or x> 9} b) all reals c) no solution

2(n-1)+4n=2(3n-1)n=0no solutioninfinitely many solutions n= - 4 !

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
