Answer 2

To calculate the expression 7.8 * 2.4 - (9.2 - 6.95) * 14.6, we can follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

First, let's calculate the expression inside the parentheses:

9.2 - 6.95 = 2.25

Next, we can substitute the result back into the main expression:

7.8 * 2.4 - 2.25 * 14.6

Now we can perform the multiplication operations:

7.8 * 2.4 = 18.72

2.25 * 14.6 = 32.85

Finally, we can subtract the results:

18.72 - 32.85 = -14.13

Therefore, the value of the expression 7.8 * 2.4 - (9.2 - 6.95) * 14.6 is approximately -14.13.
