Algebra.Com's Answer #65311 by stanbon(75887) ![]() You can put this solution on YOUR website! the length of a rectangle is 2 cm more than 5 times its width. If the area of the rectangle is 65 cm^2, find the dimensions of the rectangle to the nearest thousandth. \n" ); document.write( "----------- \n" ); document.write( "Let the width be \"x\"; then the length is \"5x+2\" \n" ); document.write( "--------- \n" ); document.write( "EQUATION: \n" ); document.write( "x(5x+2) = 65 \n" ); document.write( "5x^2+2x-65=0 \n" ); document.write( "x=[-2+-sqrt(4-4*5*-65)]/10 \n" ); document.write( "Positive solution: \n" ); document.write( "x=[-2+sqrt(1304)]/10 \n" ); document.write( "x=3.411 (width) \n" ); document.write( "5x+2=19.055 (length) \n" ); document.write( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
