How do you find 4 possible picture screens with whole number dimensions with a diagonal of 15 inches?:
\n" ); document.write( ":
\n" ); document.write( "Start with equation
\n" ); document.write( "x^2 + y^2 = 15^2
\n" ); document.write( "x^2 + W^2 = 225
\n" ); document.write( "y^2 = (225 - x^2)
\n" ); document.write( "y = \"sqrt%28225-x%5E2%29\"
\n" ); document.write( ":
\n" ); document.write( "Choose values for x that will give you an integer value for y
\n" ); document.write( ":
\n" ); document.write( "You can't unless you count x=15, y=0 and vice-versa
\n" ); document.write( "there are only two
\n" ); document.write( "x=12, y=9
\n" ); document.write( "x=9, y=12 \n" ); document.write( "
\n" );
