Which of these is a factor in this expression? 6z4 – 4 + 9 (y3 + 6)
O A. (y' + 6)
O B. 624
O C. 9 (43+6)
OD. -4+ 9 (y + 6)
please help

Is this a polynomial function? i need to know asap

Which function has the domain x> -11?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
