What is the value of the Expression
H-20 when h=60?

A:30

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

Is the figure congruent? yes or no?

I’m really confused and need your assist me with this question i’ve never been taught
