You can put this solution on YOUR website!
Given a triangle with sides:
\n" ); document.write( ".
\n" ); document.write( "3x + 7
\n" ); document.write( "4x - 9
\n" ); document.write( "5x + 6
\n" ); document.write( ".
\n" ); document.write( "To find the perimeter of this triangle, just add the three sides together. You can do this
\n" ); document.write( "by adding the columns above. That is, add 3x + 4x + 5x and you get 12x. Next add the second
\n" ); document.write( "column ... +7 -9 +6 = +4.
\n" ); document.write( ".
\n" ); document.write( "As a result of these additions you can say that the perimeter of the triangle is 12x + 4.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you understand how to do this problem.
\n" ); document.write( "
