Final answer:
To evaluate the expression, substitute the given values of x and y into the expression and simplify the result. The correct evaluation is -31.
Step-by-step explanation:
To evaluate the expression 3x² + 4x - 2y² + 4y + 5 when x is equal to -1 and y is equal to 5, we simply substitute the given values into the expression.
Plugging in x = -1 and y = 5, we get:
3(-1)² + 4(-1) - 2(5)² + 4(5) + 5
= 3 - 4 - 2(25) + 20 + 5
= 3 - 4 - 50 + 20 + 5
= -1 - 30 = -31.
Therefore, the correct evaluation of the expression is -31.
