Answer:

Choice B. only Shota

Step-by-step explanation:

16z^2 - 40z

the greatest common value is 8z

8z (2z^2 -5)

24z^2 - 40z

the greatest common value is 8z

8z (3z^2 -5)

\frac{8z (2z^2 -5)}{8z (3z^2 -5)}

8z / 8z = 1

= \frac{8z}{8z} x \frac{2z^2 -5}{3z^2 -5} = 1 x \frac{2z^2 -5}{3z^2 -5} = \frac{2z^2 -5}{3z^2 -5} (Shota)

Explain this diagram.
spayn [35]

The shape that we have here is sued to show the infinite geometric progression.

<h3>What is geometric progression?</h3>

This is the sequence of numbers that has all the other values in the sequence gotten by the multiplication of a certain factor

In this question or the shape we can see that the triangle is made up of smaller other triangles embedded in it.

The area of the traingle that is in the red color is seen to have been made up of 1/3 of the total triangles that we have in the shape. This can be seen to be similar as the triangles that are represented by the green and the blue color.

Putting a  lot of triangles inside one big triangle gives up a pictorial diagram on how to add infinite amount of things up.
