Final answer:
Simplifying the given mathematical expression step by step results in -59.813, which is not one of the provided answer choices, indicating there may be an error in the question or the options.
Step-by-step explanation:
First, let's simplify the expression step by step. The expression provided is negative 15 plus the quantity negative 3 and seven tenths plus 9 and 15 hundredths end quantity divided by 5 all times 3 squared minus 4 and 7 tenths.
- Simplify the quantity in parentheses: (-3.7 + 9.15) = 5.45
- Divide the result by 5: (5.45 / 5) = 1.09
- The next part is to calculate 3 squared, which is 3 * 3 = 9
- Now, combine the parts: (-15 + 1.09) * (9 - 4.7) = (-13.91) * (4.3)
- The final step is to multiply these two results: -13.91 * 4.3 = -59.813
Note that the final result is not among the options provided in the question, which suggests there may have been an error in the question or in the provided options.
