Which pairs of triangles can be shown to be congruent using rigid motions ? select congruent or not congruent for each pair of triangles.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer. d.289 hope that

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
