To expand \( 710(5d + 6) \), we can use the distributive property:
\[ 710(5d) + 710(6) = 3550d + 4260 \]
The correct response from the provided options is not listed, as \( 3550d + 4260 \) does not appear among the answers.
However, if you're looking for the distributed results from the operation, the step-by-step calculation leads to:
- \( 710 \times 5d = 3550d \)
- \( 710 \times 6 = 4260 \)
So \( 710(5d + 6) = 3550d + 4260 \). If you need further assistance or clarification, let me know!
