THIS IS SO HARD CAN SOMEONE HELP ME PLS:(

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 -6x - 7 y = 2

What else equals 42 and 30 for multiply
