Final answer:
The distributive property states that c(d+e) = cd + ce.
Step-by-step explanation:
The property that says c(d+e) = cd + ce is the distributive property of multiplication over addition. This property states that when you need to multiply a number (c) by the sum of two other numbers (d and e), you can distribute the multiplication to each term individually. So, c(d+e) = cd + ce.
