Algebra.Com's Answer #660104 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! width=x \n" ); document.write( "length=x+12, the width is 12 feet less, the length is 12 feet more. I could make length x and width x-12, but I'd rather deal with + than -. You get the same answer. \n" ); document.write( "x(x+12)=540. LxW=area \n" ); document.write( "x^2+12x-540=0 \n" ); document.write( "(x+30)(x-18)=0 \n" ); document.write( "x=-30, 18. Only the second answer makes sense \n" ); document.write( "width is 18 feet and length is 30 feet. \n" ); document.write( " |
