Algebra.Com's Answer #243093 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! let x=width , so 2x=length \n" ); document.write( "2 ft walkway on BOTH ends of length and width\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(x + 4)(2x + 4) = 336\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "FOILing ___ 2x^2 + 12x + 16 = 336 ___ x^2 + 6x - 160 = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "factoring ___ (x + 16)(x - 10) = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = -16 ___ and ___ x = 10 ___ negative value not realistic \n" ); document.write( " |
