Determine whether the polynomial is a difference of squares and if it is, factor it. y^2 - 225 is a difference of squares: (y - 15)^2 is not a difference of squares is a difference of squares: (y-15)(y + 15) is a difference of squares: (y + 15)^2

C

Step-by-step explanation:

  y² - 25

= y² - 5²

=  (y + 5)(y - 5) which is a difference of two squares

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
