A box contains 10 red balls and 20 yellow balls. Find the probability of choosing 3 balls that are all red, without replacement.

Solve the system of equations. y= 2x y= x^2 - 15

What is the quadric regression equation that fits these data

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
