The correct answer is D.
The symbol you are looking at is sigma, which means sum of all. Because the number on the bottom is 1 and the top is 6, these are the start and end numbers for our n value. Therefore, it means to add together all of the values of your expression (n -3), for all of the values with n equaling between 1 and 6. So let's plug in all of the numbers for n they ask for and see what we have.
1
1 - 3 = -2
2
2 - 3 = -1
3
3 - 3 = 0
4
4 - 3 = 1
5
5 - 3 = 2
6
6 - 3 = 3
Now, when we add all of these numbers up, we look for the answer.
-2 + -1 + 0 + 1 + 2 + 3 = 3
This is the answer we see in D
4,700 is one of the correct answers to this question.
The answer is -2x+4 I hope this helped
For two line segments to be parallel, their slopes must be equal.
Therefore slope of AB must be equal to slope of CD
which is, option 3
(y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)
BLUF: ANS=4.0 ft^2
Arch = Rect - (Sector - Triangle)
rect = 5.7*1.5
Sector = pi r^2 /4
= 4pi
triangle = BH /2
