Imogen bought i number of invitations to send out for her party. after she sent out 19, she was left with 11. what is the value of i?

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
