Answer:
- -1/3
- not geometric
- -5
- 4
Step-by-step explanation:
You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.
1) (2/3)/-2 = -1/3
(-2/9)/(2/3) = -1/3
(2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3
___
2) 2/0 = undefined . . . . not a geometric sequence
___
3) -10/2 = -5
50/-10 = -5
-250/50 = -5 . . . . . the common ratio is -5
___
4) 4/1 = 4
16/4 = 4
64/16 = 4 . . . . . the common ratio is 4
Well what you need to do is <span>find the perimeter of both rectangles.
Rectangle A: ((2x+8)*2)+((x-1)*2)
Rectangle B: ((3x + 5)*2)+((2x-2)*2)
That will be </span>(10x+6)-(6x+14)=4x-8
Your answer will be D.
Hope this is useful
Answer:

First, you need to find out how many words she has left to type. 2/5 of 1000 is 400, so she has 600 words left to type. Now, you have all of the information you need.
I need to know this one two :D
Use cymath to help with the math.
Solve for x in −2x−5y=−<span>3
