For this, we will be using the triangle inequality theorem, which is B+C>A\\ A+C>B\\ A+B>C


In this case, let A = 7, B = 1, and C = 7.


1+7>7\\ 8>7 (true)

7+7>1\\ 14>1 (true)

7+1>7\\ 8>7 (true)


Because all the inequalities are true, this is a possible triangle.

Find the sum of the series and show your process for finding each term leading to the final sum.
Harrizon [31]

Answer:

\sum_{k=3}^5(-2k+5)=-9

Step-by-step explanation:

The given series is:

\sum_{k=3}^5(-2k+5)

The series is not very lengthy so we can write the expanded form;

\sum_{k=3}^5(-2k+5)=(-2(3)+5)+(-2(4)+5)+(-2(5)+5)

This implies that;

\sum_{k=3}^5(-2k+5)=-1+-3+-5

\sum_{k=3}^5(-2k+5)=-9
