Algebra.Com's Answer #570097 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! \"If a>0 and b>0, compare: A. a+b B. sqrt(a^2+b^2)\"\r \n" ); document.write( "\n" ); document.write( "Here the possible answers are: \"A\" if A is greater. \"B\" if B is greater. \"C\" if both are equal, and \"D\" if there's not enough information to solve the problem. \n" ); document.write( "Can you explain it to me? \n" ); document.write( "============================== \n" ); document.write( "Square both the values A & B \n" ); document.write( "A. (a+b)^2 = a^2 + 2ab + b^2 \n" ); document.write( "B. (sqrt(a^2+b^2))^2 = a^2 + b^2 \n" ); document.write( "----- \n" ); document.write( "A^2 is greater by 2ab --> a+b is greater (by how much is not known) \n" ); document.write( " |
