Algebra.Com's Answer #38628 by Scriptor(36)![]() ![]() ![]() You can put this solution on YOUR website! Call the length = x \n" ); document.write( "Call the width = y\r \n" ); document.write( "\n" ); document.write( "You know that x*y = 48 \n" ); document.write( "You also know that x = 3y - 8\r \n" ); document.write( "\n" ); document.write( "Substitute this x in x*y=48 to obtain:\r \n" ); document.write( "\n" ); document.write( "y * (3y-8) = 48\r \n" ); document.write( "\n" ); document.write( "3y² - 8y - 48 = 0 \n" ); document.write( "Now solve this for y (delete the negative root) \n" ); document.write( "The rest of the excercise is for you :-) \n" ); document.write( "(hint: y = 4/3 + 4*sqrt(10)/3 ) \n" ); document.write( " \n" ); document.write( " |
