Final answer:
The correct answer to the calculation 8 x (3.8+13.12) - 6 is 129.36. However, this answer is not listed among the provided options, and the closest answer to this is option (c) 130 after rounding.
Step-by-step explanation:
The student is asking for assistance with a calculation involving parentheses, multiplication, and subtraction. To find the answer, we must follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, we add the numbers inside the parentheses: 3.8 + 13.12 which equals 16.92. Next, we multiply this sum by 8: 8 x 16.92. This results in 135.36. Finally, we subtract 6 from this product to get the final answer: 135.36 - 6 equals 129.36.
Therefore, the correct answer to the question 8 x (3.8+13.12) - 6 = ? is not listed exactly among the options provided, but it is closest to option (c) 130 if we are to round to the nearest whole number.
