Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation

MaReeco's rewrote equation is given by

As MaReeco subtracted 3 to the right side of the equation, which imbalanced the equation. Hence, it is not correct.
Correction:
For the next step, MaReeco should have added 3 to both sides
i.e.


Therefore, the acceptable move would have been:
Answer: Yes, they are similar- and the Scale Factor is 2.5
Step-by-step explanation: To find the scale factor, simply divide the larger number on the bigger shape by its counterpart in the smaller image, so for example: 60 divided by 24 is 2.5, and there is your scale factor. You can further test this by multiplying 4 x 2.5 which gives us 10, the other value on the larger shape.

Work Shown:

The geometric mean of two numbers has us do two steps in this order
- Multiply the values
- Apply the square root
The geometric mean can be applied to more than two values. Regardless of how many values you have, you always multiply them out. However, the number of values will tell you what kind of root you'll take (eg: 3 values leads to a cube root; 4 values means you'll take a fourth root, etc).
