Which of the following equations describes all points that are 6 units away from the point (−2, 4)

Which expression is equivalent to 2x^2+2x-4/2x^2-4x+2

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
