I'm having trouble with #10. They all seem like good answers. B is the only one I could guess on because how awkwardly it's worded.
Why? x-3 is the length of ONE side. To calculate the perimeter of a square, the 4 identical sides are added. But maybe I'm wrong, I dunno....why do you want to square it?
30. If we factorise x^2 - 6x + 9, we get (x-3)^2. So the perimeter is 4(x-3) = 4x -12 I'll need to figure out the others yet in a minute.
This equation was derived from the combined law and Avogadro's law, so if one combines these two, we get: pv/T = C (C is a constant which is directly proportional to the nr of moles of gas) And the proportionality factor so happened to be R, a constant
