Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system.

By Pythagoreans' theorem, 
7.5² = l² × b² 
56.25 = l² × b² 
Since l = b 
56.25 ÷ 2 
= l²/b²
= 28.125 mm
∴ l = √28.125 
= 5.3033 mm 
Area of square 
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)

If the original distance is x, then twice the original distance is 2x.
6 less than something means minus six, or -6.
So the answer would be A) 2x-6
