Algebra.Com's Answer #124018 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! The length of a rectangular frame is 6 cm more than the width. The area inside the frame is 55 square cm. Find the width of the frame. \n" ); document.write( ". \n" ); document.write( "Let w = width of rectangular frame \n" ); document.write( "then \n" ); document.write( "w+6 = length of rectangular frame \n" ); document.write( ". \n" ); document.write( "Area = width * length \n" ); document.write( "55 = w(w+6) \n" ); document.write( "55 = w^2+6w \n" ); document.write( "0 = w^2+6w-55 \n" ); document.write( "0 = (w+11)(w-5) \n" ); document.write( "w = {-11, 5} \n" ); document.write( ". \n" ); document.write( "We can toss out the negative solution leaving us with: \n" ); document.write( "w = 5 cm (width) \n" ); document.write( " \n" ); document.write( " |
