Actually, you have applied the distributive property of multiplication over addition in your statement, not the disruptive property. The distributive property states that for any numbers a, b, and c, a * (b + c) = a * b + a * c.
In your statement, 4(x + 5) = 4 * x + 4 * 5. By applying the distributive property, this simplifies to 4x + 20, not x + 20.
Using the disruptive property of multiplication over addition 4 (x+5) equalsx+20
