What number is less than 0 and greater than -1? thanks

I'll give brainliest if you answer right : )

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

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
