Find the required measurements of the following trapezoids. a = 8 cm b = 16 cm h = 10 cm

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

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.
