B 10

Step-by-step explanation:

so the answer would be C: 8

Step-by-step explanation:

This is because first you have to find the scale factor. The way you would find it would be by dividing one side of a triangle by the other side of the other trianle that corresponds, So for example, AB/DE=12/24=1/2

So the scale factor would 1/2.

To find x, we would have to have a number equal to 20, because it would be half of 40.

3x-4

3(5)-4

11 (A wouldn't be it, because it is not 20)

3x-4

3(10)-4

26 (B wouldn't be it, because it is not 20)

3x-4

3(8)-4

20 (C would be it, because it is 20!!!)

3x-4

3(6)-4

14 (D wouldn't be it, because it is 14)

Good luck:)

i believe a. 12x≥120 is the answer
