A construction company is planning to pour concrete for a driveway. \n" ); document.write( "The length of the driveway is 16 feet longer than its width \"w\". \n" ); document.write( "Length is \"w+16\". \n" ); document.write( "----------------------------- \n" ); document.write( "32. Write an expression for the area of the driveway. \n" ); document.write( "Area = w(w+16) = w^2+16w sq. ft. \n" ); document.write( "------------------------------------------\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "33. Find the dimensions of the driveway if it has an area of 260 square feet. \n" ); document.write( "Solve 260 = w^2+16w \n" ); document.write( "w^2+16w-260 = 0 \n" ); document.write( "(w+26)(w-10) = 0 \n" ); document.write( "Positive solution: \n" ); document.write( "width = 10 ft \n" ); document.write( "length = 10+16 = 26 ft. \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
