Answer:
Step-by-step explanation:
Input: N = 2
Output: 9
The sum of first 2 terms of Series is
3 + 6 = 9
Input: N = 3
Output: 20
The sum of first 3 terms of Series is
3 + 6 + 11 = 20
LCM stands for least common multiple, and so the LCM of two number is the smallest possible common multiple of the two numbers.
Since 16 is already a multiple of 8 (and since every number is a multiple of itself), the LCM between 8 and 16 is sixteen itself: it is a multiple of 8, it is a multiple of 16, and there couldn't be a smaller one.
Even though this case was trivial, let's do the computation to learn how to do this in general: first of all, you need the prime factorizations of the two numbers:

The LCM of the two numbers is composed by all the primes appearing in any of the two factorizations. In case a prime appears in both factorizations, we choose the one with higher exponents.
In this case, 2 is the only prime to appear in both factorizations. So, we choose the one with higher exponent, which is 4, and the answer is
, as we already observed.

Answer:
Step-by-step explanation:
Graphing systems of linear inequalities is as follows:
Step 1:
Firstly sketch first line which is in this case f(x) = x +1 which means we sketch
y = x + 1
Step 2:
Secondly we sketch the second line which is f(x) = 2 which means we sketch
y = 2
Step 3:
Thirdly we sketch the third line which is f(x) = x which means we sketch
y = x
Now since we have sketched all the three lines we see the inequalities in the first equation it says if x < 0 it means for all values of x which are less than zero meaning all the negative values meaning the graph will not exist for values of x = 0 or higher so we omit that region.
Now we for the second line it says 0 ≤ x ≤ 1 meaning the second line exists for the values of x between zero and one and the rest we omit.
Now for the third line it says x > 1 meaning the third line exists for all values of x greater than 1 meaning we omit everything else.
The rest i have attached some images on to graph the functions do take a look because typing all that would take ages so its better if you visualize it might help you understand it better.
