thank you oobleck i got the answer
To find the equivalent expression, we need to simplify the given expression step by step. Let's break it down:
1. Distribute the -5 to the terms inside the parentheses:
8 - 5(3x) + 5(7)
2. Simplify each term:
8 - 15x + 35
3. Combine like terms:
(8 + 35) - 15x
43 - 15x
Therefore, the equivalent expression is 43 - 15x. So, the correct option is D) -15x + 43.
