Write an algebraic expression to represent the new x-coordinate after a reflection across the x-axis given any initial x-coordinate, x.

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

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
