Here are some signs = + x use each sign once to make the calculation bellow correct7< > 2< > 9< > 5

1. are the triangles similar and if so why? what is the value of x? show your work.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
