Final answer:
The given expression after using the distributive property is equivalent to 16x + 24.
Step-by-step explanation:
The given expression is 3(x + 8) + 13x. We can use the distributive property to simplify this expression. Distributing 3 to (x + 8) results in 3x + 24. So the expression becomes 3x + 24 + 13x. Combining like terms, we get 16x + 24. Therefore, the expression is equivalent to 16x + 24.
