Final answer:
To simplify the expression 3 (4x + 8) using the distributive property, you need to distribute the 3 to each term inside the parentheses and then combine like terms.
Step-by-step explanation:
To simplify the expression 3 (4x + 8) using the distributive property, you need to multiply the 3 with each term inside the parentheses. This can be done by distributing the 3 to both 4x and 8. Let's break it down:
3 (4x + 8) = 3(4x) + 3(8)
Now simplify each term:
12x + 24
So, the simplified expression is 12x + 24.
