Answer 2

I can help you with this math problem. Here are the steps to solve it:

- First, we need to apply the distributive property to the terms with parentheses. We multiply the coefficient by each term inside the parentheses and add the products. For example, $$-13.9(-8.4+5.2) = -13.9 \times -8.4 + -13.9 \times 5.2$$ - Next, we need to simplify the expressions by performing the arithmetic operations. We follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. For example, $$-13.9 \times -8.4 + -13.9 \times 5.2 = 116.76 - 72.28 = 44.48$$ - Then, we need to combine the like terms by adding or subtracting them. Like terms are terms that have the same variable and exponent. In this case, there are no variables, so we just add or subtract the numbers. For example, $$44.48 - 72.85 - 29.37 - 51 = -108.74$$ - Finally, we have the answer. The value of the expression is $$-108.74$$
