Algebra/Pythagoras/Equation in Excel - Please Help - For Assignment

I still don't understand what it is you need. Your attached spreadsheet does not add any new information. Are the values in column A (0 to 6) your desired x values? And then you need to create formula for column B that will calculate the given formula [sum(sqrt(16+x^2),sqrt(45-12x+x^2))]? If this is all you need to do, it should be as easy as putting that formula into column B with references to column A. With the correct combination of relative and absolute references (in case you decide to put the constants into cells for easy editing), it should be a simple copy and paste or drag the fill handle to fill in column B (http://office.microsoft.com/en-us/ex...es_in_formulas).
