Answer:

<em>V = 16x² </em>

<em>Width = 12in</em>

<em>Height = 12in</em>

Step-by-step explanation:

Volume of the box is expressed as;

V = Length *Width * height

Given

Length = 16in

Width = x

Height = x

The volume of the box will be expressed as;

V = 16 * x * x

<em>V = 16x² (This gives the required equation)</em>

To get x:

We are given

V = 2304in³

Substitute;

2304 = 16x²

x² = 2304/16

x² = 144

3(1 – 2x) &gt; 3 – 6х help
coldgirl [10]

Answer:

<h2>\huge \: x \in ∅</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • inequality
  • distribution
  • PEMDAS
<h3>given:</h3>
  • 3(1  -  2x) > 3 - 6x
<h3>to solve:</h3>
  • x
<h3>let's solve:</h3>

step - 1  : define\\ 3(1  -  2x) > 3 - 6x

step -  2: distribute\\ 3  -  6x > 3 - 6x

step - 3  :  \\ add \: 6x \: to \: both \: sides

3  -  6x  + 6x> 3 - 6x + 6x

3 > 3

\therefore \: the \: statement \: is \: false \: for \: any \: value \: of \: x \: because \: both \: sides \: are \: identical

therefore,

x \in ∅
