Number of 16ths when 12 13/16 is changed to an improper
fraction.

Pl help

Can someone me with my hwplz(only the circled ones)

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

Can someone me do math because i am having a breakdown rn because i don’t get it
