Question

Find the scale factor

Answer 1

Answer: D) 3

Step-by-step explanation:

Focus on the horizontal sides. The jump from 3 to 9 is "times 3".

If you focus on the vertical sides, the jump from 4 to 12 is also "times 3".

Lastly, the slanted sides has a jump from 5 to 15 which is also "times 3".

This all shows the scale factor is 3. The larger triangle on the right has its sides 3 times as long compared to the smaller triangle.

Step-by-step explanation:

3*3=9

5*3=15

So you find the number that can be multiplied or divided by each side the same to get the new number
