Sagot :

To find the scale factor between two distances, we use the formula:

[tex]\[ \text{Scale Factor} = \frac{\text{Distance from } A \text{ to } B}{\text{Distance from } A \text{ to } B'} \][/tex]

Given:
- The distance from [tex]\( A \)[/tex] to [tex]\( B \)[/tex] is 10.
- The distance from [tex]\( A \)[/tex] to [tex]\( B' \)[/tex] is 2.

We can substitute these values into our formula:

[tex]\[ \text{Scale Factor} = \frac{10}{2} \][/tex]

Now, we perform the division:

[tex]\[ \frac{10}{2} = 5 \][/tex]

Therefore, the scale factor is:

[tex]\[ 5 \][/tex]

The correct answer is [tex]\( 5 \)[/tex].
