Use these clues to guess the mystery number. it is an odd number. it is greater than 142. it is less than 156. rounded to the nearest ten, the rounded value is less than the mystery number. rounded to the nearest hundred, the rounded value is greater than the mystery number. enter one number that could be the mystery number

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
