If b is the midpoint of ac, find bc (ab=3x-1 and ac=8x-20)

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

Will mark brainlist what is the slope of the line passing through the points (-2, -8) and (-3,-9)? -7/5-5/71-1

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
