Answer 2

Answer:

The answer is 15.

Step-by-step explanation:

From the question it is cleat that ,

                      x = y + 2     =>      x - y = 2

and

                      x^2 + y ^2 = 34

=>                   ( x - y )^2    = x^2 + y^2 - 2xy                

                        ( 2 )^2       = 34  -  2xy

                          4             = 34  -  2xy

                           34 - 4     = 2xy

                             2xy       =   30

                               xy       =    30/2

                               xy       =      15 .
