Some teachers adjust test scores when a test is difficult. One teacher's formula for adjusting scores is A = 253R where A is the adjusted score and R is the raw score.
If the raw scores on one test range from 27 to 64, what is the range of the adjusted
scores?

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.
