What is the distance between (1,3) and (1,-3)

Multiply. −2x(6x4−7x2+x−5) express the answer in standard form. enter your answer in the box.

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

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
