Solve for x: 0= 2y^2-8y-10

Let w=23 . what is the value of w + 45 ?

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 coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)
