Hmm, that's odd. Those are all functions from d3dx9d.lib. 2 causes can be excluded from the start:
-missing library: you'd get a different error
-old version of library: MatrixMultiply have been there for ages so it's not possible
Remains that probably the lib file is maybe corrupted? You can try to reinstall DXSDK and see if it solves the problem.
Another thing you can do is to go to Project PropertiesLinkerGeneral, set the Show Progress option to "Display All Progress Messages" and rebuild. See what you get in the Output window. Normally you should see something like this:
