Answer:

Step-by-step explanation:

Now, let's look at the direction of the shading: is it going to the left of 56 or to the right?
This shading is to the left of 56, which indicates that it's all of the numbers less than 56.

therefore, it will be x<56 (x is less than 56, and 56 is not included)
hope this helps!
