Since you have two equations that equal y, you can set them equal to themselves, so 3x+20=x^2+2x If you move those all over to one side, you get that x^2-x-20=0. From there you can factor out into two parts, (x-5)(x+4)=0. So for this set of equations you can know that the ...

Just use the equation W=F*X since it is a flat surface. There is no friction that would counteract and make this more complex. The only forces acting on the block would be the tension. In short, the work would be 300N*m or 300J, assuming that the problem is as simple as ...
