Im new to this app can someone me and u so much

Step-by-step explanation:

we have to  divide the given distance by 3.

Then we will be able to find the distance between markers.

Given distance is

Since, there are three markers,

So, we have to divide this distance by  3

So, the distance between markers is-

So, the distance between marker is

Now, we have to convert this into mixed number.

Then, the distance is-

the discriminant is 64 + 4*1*12 = 112

this is prime.
