(a) \( 6(a+4) \)

Did you know that in algebra, expressions like \( 6(a+4) \) can be simplified using the distributive property, which states that a multiplication distributes over addition? So, when you expand \( 6(a+4) \), you simply multiply \( 6 \) by both \( a \) and \( 4 \), giving you \( 6a + 24 \). It's like spreading joy equally to both friends! If you're ever uncertain about applying the distributive property, just remember this common pitfall: forgetting to multiply each term inside the parentheses! A classic mistake is writing \( 6a + 4 \) instead of \( 6a + 24 \). Just take a moment to review your work, and you’ll be golden!
