Is 31 composite or prime and is 62 composite or prime

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.

Which equation represents the function on the graph?

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
