The correct answer is C
Sigma Notation is when we take all of the whole numbers between the starting point (which can be found as the number under the sigma sign) and the end number (which can be found above the sigma sign). Therefore, we will add together all of the values of 3k + 2 for when k is equal to all of the numbers between 2 and 7. So, let's evaluate each one first.
When k = 2
3(2) + 2 = 8
When k = 3
3(3) + 2 = 11
When k = 4
3(4) + 2 = 14
When k = 5
3(5) + 2 = 17
When k = 6
3(6) + 2 = 20
When k = 7
3(7) + 2 = 23
So we know we have the following.
8 + 11 + 14 + 17 + 20 + 23
Now for the number after the comma, we are just looking for the answer of them all added together. So the final answer should be
8 + 11 + 14 + 17 + 20 + 23, 93
It would be 25000 no decimal or fraction 25,000.0

Answer: angle U = 72 degrees</h3>
===================================================
Explanation:
If you have n sides of a polygon, then the interior angles add up to S = 180(n-2)
In this case, n = 5, so S = 180(n-2) = 180(5-2) = 540
We can add up the five angles the diagram shows and set that sum equal to 540 to solve for x
S+T+U+V+W = 540
90+2x+x+2x+90 = 540
5x+180 = 540
5x = 540-180
5x = 360
x = 360/5
x = 72
Since angle U = x, this means angle U = 72 degrees
