You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
5/12 - 4/5 = -23/60. You can't simplify -23/60. Hope this is right
Answer:we know that all 3 sides are equal
so if side =a
then perimeter =3a
therefore
3a=6n-15
a=6n-15/3
a=2n-5
The mode is the number repeated most often, so if we arrange these numbers in order, we can see what numbers repeat the most-
1 1 1 2 3 3 5 7 8 8 9
The number that repeats the most is 1
(1 counted 3 times)
(3 counted twice)
(8 counted twice)
16 is the answer to this question.
