Final answer:
The expression 5(x+8) can be rewritten as 5x+40 using the distributive property.
Step-by-step explanation:
The expression 5(x+8) can be rewritten using the distributive property, which states that when you multiply a number by a sum or difference, you can distribute the number to each term in the parentheses. Applying the distributive property to 5(x+8), we would multiply 5 by both x and 8. This yields the expression 5x+40, which is the correct answer choice.
