Find the missing length, when the perimeter is 9x+11. They give me 2 lengths: 2x+3 and 3x+1 how could I find the missing length x? would I add 2x+3+3x+1? and then subtract the total by 9x+11?

oh ok :) So then, would I multiply 60x100=6000 and 30x50=1500 then subtract 6000-1500?

the problem is about adding and subtracting polynomials... This is what I did... 2x+3+3x+1 =2x+3x+3+1 =5x+4 and 9x+11-5x+4 =9x-5x+11+4 =4x+15 but then, if I add both 5x+4+4x+15 =9x+19...

The key is static friction, a frictional force that prevents two surfaces from sliding over one another. In this case, as you open the door, static friction caused by the ground essentially keeps you "anchored" and the door's force has no effect on you.
