Algebra.Com's Answer #533830 by Alan3354(69443) You can put this solution on YOUR website! evaluate \n" ); document.write( "6 4 7 \n" ); document.write( "4 2 0 \n" ); document.write( "2 6 5 \n" ); document.write( "===== \n" ); document.write( "= 6*(10) - 4*(20) + 7*(24-4) = 60 - 80 + 140 \n" ); document.write( "= 120 (if you mean the determinant) \n" ); document.write( "---------------- \n" ); document.write( "I don't know if the 1st one is 60. Might be, might not. \n" ); document.write( "----------------------------- \n" ); document.write( "All the elements in the middle column are doubled, so the 1st one is 60. \n" ); document.write( " |
