Answer 3

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's apply this to the given expression:

-3.5 * (15.2 - 21.2)

First, calculate the subtraction inside the parentheses:

15.2 - 21.2 = -6

Now substitute the result back into the expression:

-3.5 * (-6)

Multiply the numbers:

-3.5 * -6 = 21

So, the result of the expression is 21.
