The combined area of the two black squares is equal to 1000 square units. A side of the larger black square is 8 units longer than a side of the smaller black square. What is the combined area of the two white rectangles in square units?
Choose one:	A) 928	B) 936	C) 948	D) 968	E) 972
The length of a smaller square - x;   The length of a larger square - x+8;   The area of entire square - x^2+(x+8)^2=1000 --&gt; 2x^2+16x=936;   The combined area of the two white rectangles - x(x+8)+x(x+8)=2x^2+16x --&gt; look up: 2x^2+16x=936.   Answer: 936.
