Algebra.Com's Answer #403680 by stanbon(75887)![\"\"](\"/images/stars/stars-13.gif\")   You can put this solution on YOUR website! A rectangular field has an area of 10 square meters. If its length is one meter less than 3 times its width, what are its dimensions? \n" ); document.write( "-------------------- \n" ); document.write( "Let the width be \"x\" \n" ); document.write( "Length is \"3x-1\". \n" ); document.write( "-------- \n" ); document.write( "Equation: \n" ); document.write( "width*length = 10 meters \n" ); document.write( "x(3x-1) = 10 \n" ); document.write( "3x^2 - 3x - 10 = 0 \n" ); document.write( "x = [3 +- sqrt(9-4*3*-10)]/6 \n" ); document.write( "------ \n" ); document.write( "Positive solution: \n" ); document.write( "x = [3 + sqrt(129)]/6 \n" ); document.write( "x = 2.39.. meters (width) \n" ); document.write( "3x-1 = 6.18.. meters (length) \n" ); document.write( "============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "==================\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
