I DID NOT COME UP WITH THE SAME ANSWER AS YOU BUT WE ARE FAIRLY CLOSE. MAYBE YOU CAN CHECK BOTH OUR SOLUTIONS----PTAYLOR\r

\n" ); document.write( "\n" ); document.write( "In a right triangle, the Pythagorean Theorem states\"c%5E2=a%5E2%2Bb%5E2%29\" where c is the hypotenuse and a and b are the respective sides.\r
\n" ); document.write( "\n" ); document.write( "Let x= width of rectangle\r
\n" ); document.write( "\n" ); document.write( "Then x+1=length of rectangle
\n" ); document.write( "We are told that the diagonal or{or hypotenuse of the triangle) is 4 cm. So or equation to solve is:\r

\n" ); document.write( "\"x%5E2%2Bx%5E2%2B2x%2B1=16\" subtract 16 from both sides
\n" ); document.write( "\"2x%5E2%2B2x-15=0\" quadratic in standard form\r
