The lengths of the sides of a triangle are consecutive even integers. The perimeter is 22cm shorter than 4 times the length of the longest side. Find the lengths of all three sides.\r
\n" ); document.write( "\n" ); document.write( "ANswer\r
\n" ); document.write( "\n" ); document.write( "sides: x , x+2 and x+4\r
\n" ); document.write( "\n" ); document.write( "Perimeter = x+(x+2)+(x+4) = 3x+6\r
\n" ); document.write( "\n" ); document.write( "then: 3x+6 = 4(x+4)-22\r
\n" ); document.write( "\n" ); document.write( "3x+6 = 4x-6\r
\n" ); document.write( "\n" ); document.write( "3x-4x = -6-6\r
\n" ); document.write( "\n" ); document.write( "-x = -12\r
\n" ); document.write( "\n" ); document.write( "x = 12\r
\n" ); document.write( "\n" ); document.write( "sides: 12, 14 and 16\r
