You can put this solution on YOUR website!
What are your complete instructions? Are you plugging in x=0 and evaluating for T? If you are, then you're not going to get T=13 as an answer. So are you supposed to plug in some other value of x? Or are you trying to solve for x? You need to post the whole problem (including the question/instructions). \n" ); document.write( "
