Since jane weighs 126 and is gaining 3 pounds per month that would make the part of the equation that is 126+3m and since Cynthia weighs 134 and is gaining 2 pounds every month that is what makes the 134+2m part of the equation. And since the equation is 134+2m=126+3m then the goal is to find how many months it would take for their weights' to be equal. Sorry that my explaining skills are terrible hopefully I helped a little.
6,000 = 6 x 10^3 square meters. 6,000 = 60 x 10^2 square meters 6,000 = 600 x 10^1 square meters. You can pick which you wish to report in. Hope this helps :-)
