The temperature on a summer day is 77 degree fahrenheit , the formula convert temperature to degrees celsius =5/9 (f-32). what is the corresponding temperature in degrees celcius?

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
