Algebra.Com's Answer #69201 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! let x=width so 3x=length ... area=width*length ... 75=x*3x ... 75=3x^2 ... 3x^2-75=0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "dividing by 3 gives x^2-25=0 ... difference of two squares factors to (x+5)(x-5)=0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x=5 and x=-5 ... negative is not realistic ... dimensions are 5 and 15 \n" ); document.write( " |
