if x+y=4, What is the perimeter of a square with side length 2x^2+4xy+2y^2
\n" ); document.write( ":
\n" ); document.write( "2x^2 + 4xy + 2y^2
\n" ); document.write( "Factor
\n" ); document.write( "2(x^2 + 2xy + y^2)
\n" ); document.write( "Factor
\n" ); document.write( "2(x+y)(x+y)
\n" ); document.write( "Given that x + y = 4
\n" ); document.write( "2(4)(4) = 32, the side lengh
\n" ); document.write( "then
\n" ); document.write( "4(32) = 128 is the perimeter of the square \n" ); document.write( "
\n" );
