The area of a square is subtracted from one of its sides, and the perimeter is then added to this total, the result is 4. What is the length of one side? Select:
A) 1 B) 2 C) 3 D) 4 E) 5
The equation is; side - Area + Perimeter = s - A + P = s - s^2 + 4s = s(1 - s + 4).   By plugging in the answers we can test the answers quickly; then, 4 is the only possible answer.   1nswer: 1
