You've got to get the right picture
\n" ); document.write( "width = w
\n" ); document.write( "length = w + 3
\n" ); document.write( "The 2\" border actually adds 4\" to the width and 4\" to the length.
\n" ); document.write( "That's because there's 2\" on each side of the photo
\n" ); document.write( "\"%28w+%2B+2+%2B+2%29%2A%28w+%2B+3+%2B+2+%2B+2%29+=+108\"
\n" ); document.write( "\"w+%2B+4%29%2A%28w+%2B+7%29+=+108\"
\n" ); document.write( "\"w%5E2+%2B+11w+%2B+28+=+108\"
\n" ); document.write( "\"w%5E2+%2B+11w+-+80+=+0\"
\n" ); document.write( "complete the square
\n" ); document.write( "\"w%5E2+%2B+11w+%2B+%2811%2F2%29%5E2+=+80+%2B+%2811%2F2%29%5E2\"
\n" ); document.write( "\"%28w+%2B+11%2F2%29%5E2+=+320%2F4+%2B+121%2F4\"
\n" ); document.write( "take square root of both sides
\n" ); document.write( "\"%28w+%2B+11%2F2%29%5E2+=+441%2F4\"
\n" ); document.write( "take the square root of both sides
\n" ); document.write( "\"w+%2B+11%2F2+=+21%2F2\"
\n" ); document.write( "\"w+=+10%2F2\"
\n" ); document.write( "\"w+=+5\"
\n" ); document.write( "\"w+%2B+3+=+8\"
\n" ); document.write( "so, it's a 5x8 photo
\n" ); document.write( "check
\n" ); document.write( "\"%28w+%2B+4%29%2A%28w+%2B+7%29+=+108\"
\n" ); document.write( "\"%285+%2B+4%29%2A%285+%2B+7%29+=+108\"
\n" ); document.write( "\"9%2A12+=+108\"
\n" ); document.write( "\"108+=+108\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
