Answer 2

1. To evaluate the expression 2.5x2 when x = 4, you simply substitute the value of x into the expression and perform the multiplication:

2.5 * 2 = 5

So, when x = 4, the expression 2.5x2 evaluates to 5.

2. To evaluate the expression 5xy when x = 3 and y = 2, you substitute the given values into the expression and perform the multiplication:

5 * 3 * 2 = 30

So, when x = 3 and y = 2, the expression 5xy evaluates to 30.
