You "distributed" the negation inside the parenthesis. Let's focus on the part.
We can distribute the negation inside the parenthesis by negating every term, and switching and with or, and vice versa. So, you have
Of course, writing is improper, I was just stressing the fact that we distributed the negation to every term in the parenthesis. So, since a double negation cancels out, you're left with
which of course implies that
Edit: I actually derived the expression in the opposite order, but since they are equivalent, it doesn't really matters where you start from and where you get to. Anyway, if you actually want to derive from , you simply have to negate the first parenthesis and distribute the negation as discussed.

Answer:
10 points
Step-by-step explanation:
per 2 days you lose 5 points. To get to 4 days you multiply 2 by 2 and get 4 and 5 by 2 and get 10. So per 4 days he loses 10 points.
Answer:
<h2>
204π units²</h2>
Step-by-step explanation:
The lateral area of the cylinder includes both the side and the ends.
The area of the side can be found by calculating the circumference of the cylinder and multiplying that by the height: A = 2π(6 units )(11 units) = 132π units².
The area of one end of this cylinder can be found by applying the "area of a circle" formula: A = πr². Here, with r = 6 units, A = π(6 units)² = 36π units². Since the cylinder has two ends, the total area of the ends is thus 2(36π units) = 72π units.
The total lateral area of the cylinder is thus 72π units² + 132π units², or 204π units²
