Answer: 122
Step-by-step explanation:
Since it is a geometric sequence, lets see the pattern below:
From this, we can see that we multiply each number by -3 to get the next number.
Before we find the sum, we first find the next number.
-54×-3=162
So the whole sequence will be: 2, -6, 18, -54, 162
Find the sum
2+(-6)+18+(-54)+162
=2-6+18-54+162
=-4-36+162
=-40+162
=122
Hope this helps!! :)

Answer:
It's C) -6y
Step-by-step explanation:
I know someone already answered but I figured I could explain since it looks like you are getting a little confused. The reason it's not A is because its
-5 + 5 which is zero. So it gets rid of x so your just left with -6y. If it was
5x+5x then it would 10x but the negative makes it 0
Answer:
????? umm whaat did you forget to add image
We know the area = 35/4 and length = 7/2. We are looking for the width.
Area = length * width
35/4 = (7/2) * width
Divide both sides by 7/2: (35/4)/(7/2) = width
Width = (35/4)*(2/7)
Width = 5/2 (answer)
