If A = 22 - 712 + 3 and B = 4x2 - 12x, what is A + B? O 322 - 102 +3
O 6.2 - 71 - 9
O-322 + 10x + 3
037² – 10x + 3

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

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
