Which is the area of a circle with a radius of 5 units? (use 3.14 for ) A. 15.7 square units B. 31.4 square units C. 78.5 square units D. 392.5 square units

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

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

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression
