Final answer:
The evaluation of |8-t|+3 with t=3 results in 8, which is not included in the provided answer choices.
Step-by-step explanation:
The question provided requires evaluating an absolute value expression and then performing an addition. Given the values R=-2, n=-3, t=3, we need to evaluate |8-t|+3.
Firstly, we replace t with 3 to find the absolute value: |8-3|, which simplifies to |5|, and the absolute value of 5 is 5.
Now, we simply add 3 to our result: 5 + 3, which equals to 8.
None of the provided options A) 10, B) 12, C) 14, D) 16 match our result, which suggests there might have been a typo in the options or in the question.
