2
(x+4)
(5x-3)
3
(3x+5)
(5x+3)
(x-4)
(3x-5)

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

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.
