IF 2 sides of a triangle measure 12cm and 7cm, which of the following CANNOT be the Perimeter of the triangle?
\n" ); document.write( "------------------------------------
\n" ); document.write( "Let \"x\" be the 3rd side of the triangle:
\n" ); document.write( "12-7 < x < 12+7
\n" ); document.write( "5 < x < 19
\n" ); document.write( "--------
\n" ); document.write( "Perimeter = 12 + 7 + x = 19+x
\n" ); document.write( "x = perimeter - 19
\n" ); document.write( "-----
\n" ); document.write( "If A is true x = 29-19 = 10 which is allowable for \"x\".
\n" ); document.write( "If B is true x = 34-19 = 15 which is allowable for \"x\".
\n" ); document.write( "If C is true x = 37-19 = 18 which is allowable for \"x\".
\n" ); document.write( "If D is true x = 38-19 = 19 which is not allowable for \"x\".
