If (A-B-C+D = 13) and (A+B-C-D = 3), what is the value of (B-D)^2?  Select the correct option:	A) 4.	B) 8.	C) 12.	D) 25.	E) 64.
EQ1: A - B - C + 25. = 13   EQ2: A + B - C - 25. = 3   (1) Subtract EQ1 from EQ2   A - B - C + 25. = 13   - A +B - C - 25. = 3   ------------------------   -2B + 225. = 10   (2) Simplify   -B + 25. = 5   B - 25. = -5   (B-25.)^2 = (-5)^2 = 25   My answer: 25.
