Algebra.Com's Answer #69046 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Let W=width of rectangle\r \n" ); document.write( "\n" ); document.write( "Now we know that the area of a rectangle =Length times Width. So:\r \n" ); document.write( "\n" ); document.write( "3x^2+5x=x*W we can rewrite this as follows:\r \n" ); document.write( "\n" ); document.write( "x(3x+5)=x*W divide both sides by x (x cannot be equal to zero)\r \n" ); document.write( "\n" ); document.write( "W=3x+5-----------------------ans\r \n" ); document.write( "\n" ); document.write( "CK\r \n" ); document.write( "\n" ); document.write( "x(3x+5)=3x^2+5x \n" ); document.write( "3x^2+5x=3x^2+5x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
