Find the circumference of this circle
using 3 for T.
C [?]

Evaluate-27 ^4/3/8 a) - 81/16 b) 81/16 c) 16/81

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

What is the the greatest common factor ?
