The trail starts at p(−2, 2) and goes to q(5, 2).
it goes from q to r(5, −5) and then to s(8, −5).

what is the total length (in units) of the biking trail?

Use the distance formula for each set of points, then add them all together to get the total length of the trail :)

Idon’t know what the answer is i wish i could

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
