the base of a triangle has the same length as a side of a square.
\n" ); document.write( " the second side of the triangle is 2 inches longer than the base, and the third side is 6 inches longer than the base.
\n" ); document.write( " if the perimeter of the triangle equals that of the square, find the longest side of the triangle.
\n" ); document.write( ":
\n" ); document.write( "let x = the side of the triangle that is the also the side of the square
\n" ); document.write( "then
\n" ); document.write( "(x+2) = the 2nd side of the triangle
\n" ); document.write( "nad
\n" ); document.write( "(x+6) = the 3rd side
\n" ); document.write( ":
\n" ); document.write( "perimeter equation
\n" ); document.write( "4x = x + (x+2) + (x+6)
\n" ); document.write( "combine like terms
\n" ); document.write( "4x = 3x + 8
\n" ); document.write( "4x - 3x = 8
\n" ); document.write( "x = 8 is the length of the base
\n" ); document.write( "and
\n" ); document.write( "8 + 6 = 14 is the length of the longest side of the triangle \n" ); document.write( "
\n" );
