Algebra.Com's Answer #527109 by ewatrrr(24785) You can put this solution on YOUR website! A = Lw = 40in^2 \n" ); document.write( " (w+3)w = 40 \n" ); document.write( "w^2 + 3w - 40 = 0 \n" ); document.write( "(w + 8)(w-5) = 0, tossing out negative solution for unit measure \n" ); document.write( "w = 5in and L = 8in \n" ); document.write( " \n" ); document.write( " |
