Answer 2

Calculating the Expression -3.8*(4-4.9)+13.4*(3-2.8)

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

1. Solving the Expression Step by Step:

- First, we'll solve the expressions within the parentheses: - For the expression inside the first set of parentheses (4-4.9): - 4 - 4.9 = -0.9 - For the expression inside the second set of parentheses (3-2.8): - 3 - 2.8 = 0.2

- Then, we'll perform the multiplication and subtraction operations: - -3.8 * (-0.9) = 3.42 - 13.4 * 0.2 = 2.68 - 3.42 + 2.68 = 6.1

2. Final Result: - Therefore, the value of the given expression -3.8*(4-4.9)+13.4*(3-2.8) is 6.1.

Conclusion

The given expression -3.8*(4-4.9)+13.4*(3-2.8) evaluates to 6.1 after following the order of operations.
