Answer:

<h2>2. Combining old and new observations.</h2>

Step-by-step explanation:

Through the passage, Nicholas Copernicus is introducing to the reader a new worlds, based on observations from the pass, and recent observations made by scientists. Basically, he's talking about a work where the reader is going to able to learn and be aware about the stars and planets movements in a way that no one could imagine before.

Copernicus specifically states that those observations are based on ancient and new data.

Therefore, the right answer is 2, because it's a combination of old and new observations.

The rule of the volume of the rectangular prism is

$V=L\times W\times H$

L is the length

W is the width

H is the height

From the attached picture we can see

L = (2x - 3)

W = (x + 1)

H = (3x + 4)

We will substitute them in the rule above

$V=(2x-3)(x+1)(3x+4)$

We will multiply the first 2 brackets, then multiply the answer by the 3rd bracket

$\begin{gathered} (2x-3)(x+1)=(2x)(x)+(2x)(1)+(-3)(x)+(-3)(1) \\ (2x-3)(x+1)=2x^2+2x-3x-3 \\ (2x-3)(x+1)=2x^2-x-3 \end{gathered}$

Multiply this answer by the 3rd bracket

$\begin{gathered} (2x^2-x-3)(3x+4)= \\ \left(2x^2\right)\left(3x\right)+\left(2x^2\right)\left(4\right)+\left(-x\right)(3x)+(-x)(4)+(-3)(3x)+(-3)(4)= \\ 6x^3+8x^2-3x^2-4x-9x-12= \\ 6x^3+5x^2-13x-12 \end{gathered}$

Then the volume of the prism is

$V=6x^3+5x^2-13x-12$

The answer is the 2nd choice

96 = 12f<br><br><br><br><br><br>help please please

You can do anything to an equation as long as you do it to both sides

divide both sides by 12
96/12=(12f)/12
48/6=(12/12)f
24/3=1(f)
8/1=f
8=f
