You need two terms that multiply to (12x-4). The term on the outside needs to be a common multiple of 12 and 4. The common factors are 1, 2, and 4. Here are the following possible dimensions:
1(12x-4)
2(6x-2)
4(3x-1)
Hope this helps.

Answer:

13 trails

Step-by-step explanation:

The histogram shows following numbers of trails:

0 - 6 km long - 5 trails;
6 - 12 km long - 9 trails;
12 - 18 km long - 7 trails;
18 - 24 km long - 3 trails;
24 - 30 km long - 4 trails;
30 - 36 km long - 1 trail;
36 - 42 km long - 3 trails.

So, there are 5 trails with length less than 6 km and 4 + 1 + 3 = 8 trails that are at least 24 km long.

In total, 5 + 8 = 13 trails
