3. simplify the expression.
9xy2 – 11xy2

If a baby uses 15 diapers in 2 days, how many diapers will the baby use in a year?

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
