Triangle XYZ has vertices X(3,−1),Y(5,−4),&Z(1,−5). Graph △XYZ and its image after a 180∘ rotation clockwise about the origin. Then give the coordinates of the vertices for △X′Y′Z′.

78.59 is the mean

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

answer is
