the center of the milky way is approximately 25,000 light years away from the earth. Earth is 1.58 x 10^-5

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Write an equation of the line that passes through the point (2, 3) and is perpendicular to the line x = -1. a) y = 1 b) y = 3 c) y = 0 eliminate d) y = -3
