2. If p(x) = 7x-9 and g(x) = x2 +8, what is r(x) = (p * 2)(x)?​

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

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