${ \left( 2+y \right) }^{ 3 }\\ \\ =\left( 2+y \right) \left( 2+y \right) \left( 2+y \right) \\ \\ =\left( 2+y \right) \left( 4+4y+{ y }^{ 2 } \right)$

$\\ \\ =2\left( 4+4y+{ y }^{ 2 } \right) +y\left( 4+4y+{ y }^{ 2 } \right) \\ \\ =8+8y+2{ y }^{ 2 }+4y+4{ y }^{ 2 }+{ y }^{ 3 }\\ \\ ={ y }^{ 3 }+6{ y }^{ 2 }+12y+8$

Nicole is playing a video game where each round lasts 3/44 of an hour. She has scheduled 3 3/4 hours to play the game. How many

Marrrta [24]

Let's not think about the problem, let's think about the fractions and dividing. We're are trying to find how many sets of 3/44 are in 3 3/4. We need to divide. Using keep change and flip, we can divide successfully.
Let's make sure the first fraction is improper.
15/4÷3/44=?
Keep, Change, and Flip.
15/4×44/3
660/12
Let's simplify.
55.
So Nicole can play 55 rounds.

Step-by-step explanation:

Well, since there is no image I thought I would provide what a rectangle would probably look like in your case. The rectangle can be split into half parts 4 ways.

<h2>Ways it can be Split:</h2>

1. We can split it the hotdog way, or staright down the rectangle (drawing provided down below)

2. We can split it the Hamburger way, again drawing is provided.

3. We can split it from the top-left corner to the bottom-right, and the opposite way around.
