The expression 7(3 + 55) = 7 x 3 + 7 x 5 exemplifies the distributive property because it demonstrates how multiplication distributes over addition. In this case, multiplying the number 7 by the entire quantity (3 + 55) means that you can also multiply 7 by each individual addend (3 and 55) separately and then add the results together.

This property essentially allows you to break down the expression into simpler parts, making calculations easier and showcasing the relationship between multiplication and addition. It illustrates that the sum inside the parentheses can be distributed across the multiplication with 7, yielding equivalent results.
