How many positive integers n are there which satisfy n^2-15n+14< 0？

13

Step-by-step explanation:

given

n²-15n+14<0

factorize

we get

(n-14)(n-1)<0

n<14. & n<1

here we neglect the second one

coz there is no positive integer less than 1

so n<14

there are 13 integers which satisfy the inequation

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
