The diagonal of a rectangle is 25 inches more than its width. The length of the rectangle is 23 inches more than its width. What is the width of the rectangle?

\n" ); document.write( "Use pythag: a^2 + b^2 = c^2
\n" ); document.write( ":
\n" ); document.write( "Let b = width
\n" ); document.write( "then
