Josh rides his bike along a 9-mile trail. there are trail markers every 13 mile. the markers start at 13 mile and end at 9 miles. how many markers does josh see on the trail?

So this means that we have to multiply since it says that he rides his bike along a 9-mile trail. Then it says There are trail markers every 13 mile so we have to do 9x3= 27 and then I would think you do 27+13 which equals 40. So he say 40 markers on the trail. (Also show your work) :)

31 is prime. and it’s prime factorization is just 31.
