Graph for ( sqrt ( cos ( x )) ) * cos ( 300 * x ) + sqrt ( abs ( x )) - 0.7 ) * ( 4 - x * x ) ^ 0.01 , sqrt ( 6 - x ^ 2 ) , -sqrt ( 6 - x ^ 2 ) :)))

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,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.

1. are the corresponding angles congruent 2. find the ratios of the corresponding sides 3. is triangle jkl congruent to triangle rst? if so what is the scale factor
