Hi all,

I'm looking for very specific information, answers, or directions to websites that contain this information (and that the person answering has verified).

I have a few (Ontarian) cities in mind that I am considering moving to and I would like to compare the cost of living between these cities. I'm having difficulty finding any trustworthy and reliable sources that provide cost of living comparison information. I tried, unsuccessfully, to locate this information on Statistics Canada's website (but that doesn't mean it's not hidden on there somewhere).

The cities that I'm looking to get this information are located in Ontario, Canada and their names are as follows:
--London
--Ottawa
--Kingston
--Woodstock
--Brockville
--Pembroke

If someone can actually locate some solid information on this, I'd be grateful!

Thanks,

Jamie

Find the length of the unknown side of the triangle. Give the exact length and a one-decimal-place approximation.
length of one side is 5m. and the longer side of the triangle is 9 and the sqaure root of 3m ( the 3m is under the radical sign and the 9 is on the outside of the radical sign.). this is the only one that I have and I need some help please on how to get the answer. I know the formula is a^2+b^2=c^2
but it keep coming up wrong and I need to get the length in length and the decimal length. I'm not doing something right.help please
