Answer:

Step-by-step explanation:
Let 's' be the side of the original square
the length of the side of a square is doubled, so the length of the new square is 2s
Area of the original square with side length 's' is 
Area of the new square with side length '2s' is 
Area of the new square is 4 times the area of the original square
ratio of the areas of the original square to the area of the new square

Answer:
a_0 = -27
a_n = a_(n-1) * (-1/3)
Step-by-step explanation:
First evaluate given formula at n=0 and specify that as starting value
Then find how to get from n-1 to n by comparing two values. In this case the next value is formed by multiplying by -1/3.
Multiply principle by time by rate
1200(.02)(5)
120
So its asking for basically the percentage of the first number out of the second.
3. 25/50 = 50%
4. 125/75 = 167%
5. 32/28 = 114%
6. 7/10 = 70%
Hope this helped! :)
Answer:
x - 
Step-by-step explanation:
y = x + 10/7
x = y + 10/7
x = y + 10/7
x - 10/7 = y
y = x - 10/7
x -
