Hello!
In this question, we can relate the definition of similar polygons to the side lengths.
If two given polygons are similar, that means that each corresponding side is multiplied by a certain, equivalent ratio to get the side length of the other side.
That means that we can take any side length ratio and set it equal to a ratio including the unknown side length.

![8.4=2x](https://tex.z-dn.net/?f=8.4%3D2x)
![x=4.2](https://tex.z-dn.net/?f=x%3D4.2)
Hope this helps!

Answer:
A. x^2 + 6
Step-by-step explanation:
(4x^2 - 6x + 8) - (3x^2 - 6x + 2) =
The first set of parentheses is unnecessary, so just remove it.
= 4x^2 - 6x + 8 - (3x^2 - 6x + 2)
To remove the second set of parentheses, change the sign of each term inside.
= 4x^2 - 6x + 8 - 3x^2 + 6x - 2
Now combine like terms.
= x^2 + 6
