In the 30-60-90 triangle below side s has a length of and side r has a length

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

The square root of 9x plus 7 plus the square rot of 2x equall to 7
