Answer:

2^n pieces

80 / (2^n) in²

Step-by-step explanation:

If she cuts the paper in half 1 time, she will have 2 pieces.

If she cuts the paper in half 2 times, she will have 4 pieces.

If she cuts the paper in half 3 times, she will have 8 pieces.

So the pattern is 2^n.

The original area is 80 in². Divided by 2^n pieces means each piece has an area of 80 / (2^n) in².

15c² - 5c. Factorise completely

KATRIN_1 [288]

Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is $15c^2 - 5c$ .

The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both $15c^2$ and $-5c$ have the number 5 and the variable c associated with them so we can factor out those two.
