In APQR, PR is extended through point R to point S, mZQRS = (7x+8)°, mZRPQ = (x +12)', and mZPQR= (3x + 20°. Find mZRPQ.

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 check if i did this right since i really want to make sure it’s correct. if you do you so much
