P(x) = -5x2 - 10x - 2
(Graphing quadratic functions in the form f(c) =ax^2 + bc + c)

Aline parallel to a triangle's side splits ab into lengths of x - 5 and x + 2. the other side, ac, is split into lengths of x and x + 12. what is the length of ac? a) 12 b) 24 c) 36 d)

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

Joey is asked to name a quadrilateral that is also a rhombus and has 2 pairs of parallel sides.should be his answer
