A plane travels from Des Moines to Phoenix, on to Atlanta, and then completes the trip directly back to Des Moines as shown on the diagram. Write the lengths of the legs of the trip in order from greatest to least. Des Moines Phoenix to Atlanta Des Moines to Phoenix Atlanta to Des Moines (8x + 4)o (5x + 21)o (11x – 37)o Phoenix Atlanta
