Algebra.Com's Answer #22718 by checkley71(8403) ![]() You can put this solution on YOUR website! (30+X)*(20+X)=2*(30*20) OR 600+50X+X~2=2*600 OR 600+50X+X~2=1200 OR X~2+50X-600\r \n" ); document.write( "\n" ); document.write( "OR (X+60)(X-10)=0 OR X=10 OR 40*30=1200 OR 1200=1200 \r \n" ); document.write( "\n" ); document.write( "10 METERS ARE ADDED TO THE LENGTH & THE WIDTH \n" ); document.write( " |
