Lewis drove 14 miles north and 48 miles east. On his return trip he drove home diagonally. How much shorter was the return trip?

12 miles, Because using the Pythagorean theorem, A squared plus B squared = C squared. So 14 squared +48 squared equals 2500. The square root of 2500 is 50, so the total of 14+48 is 62-50 is 12 miles shorter

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
