Evaluate and simplify the expression
when x= 3 and y = 5.
2y + 3(x - y) + x2 = [ ? ]

13

Step-by-step explanation:

x = 3 & y = 5

2y + 3(x - y) + x² = 2*5 + 3(3 - 5) + 3²

                          = 2*5 + 3*(-2) + 3²

                         = 10 - 6 + 9

                        = 4 + 9

                        = 13
