To expand the expression \( 710(5d + 6) \), you apply the distributive property:
\[ 710(5d + 6) = 710 \cdot 5d + 710 \cdot 6 \]
Now, calculate each term:
- \( 710 \cdot 5d = 3550d \)
- \( 710 \cdot 6 = 4260 \)
Putting it all together, we get:
\[ 710(5d + 6) = 3550d + 4260 \]
So, the expanded expression is:
\[ 3550d + 4260 \]
