To distribute in the expression 4x(y + 7), we need to know what the word distribute means. In mathematics, the distributive property is the property that says a(b + c) = a(b) + a(c). Since the question is asking us to distribute, this is what the question is asking us to do, just with different numbers. The expression becomes:
4x(y) + 4x(7)
Simplifying, we get our answer of:
4xy + 28x
