Help me with this ( fake answers will be reported :)) )

If lmn=xyz, which congruences are true by cpctc? check all that apply

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

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?
