If x=2 and y = 5, evaluate 5xy — $$y^2$$​​

Correct option is B

Given:
x = 2, y = 5
The expression to evaluate is 5xy - y².
Formula Used:
Direct substitution of values into the given expression.
Solution: Substitute the values of x and y into the expression:
5xy - y² = 5(2)(5) - (5²)
First, calculate 5xy:
5 × 2 × 5 = 50
Now, calculate y²:
5² = 25
Substitute these values into the expression:
50 - 25 = 25
Thus, the value of the expression is 25.
Final Answer: (b) 25
