Which expression is equivalent to 6(3+0.05)?

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .
