5(x + y)

Work Step by Step

Using the distributive property, we know that multiplying a number, like 5, by two terms (x and y) individually and then adding the result is the same as multiplying 5 by the sum of x and y. Thus, knowing that both x and y and multiplied by 5, we can rewrite the expression using the distributive property like this: 5x + 5y = 5(x + y)
