Answer:
1.)Geometric
2.)Arithmetic
3.)Arithmetic
4.)Arithmetic
5.)Geometric
Step-by-step explanation:
Geometric is here you multiply or divide the same number to different numbers to get a sequence. Arithmetic is where you ad or subtract.
As it has been given that 
, 
.
We need to find the value of the following:
(i) 
, substituting the value of 'x' and 'y' in the expression, we get:
So, 
(ii) 
, substituting the value of 'x' and 'y' in the expression, we get:
So, 
(iii) 
, we need to substitute the value of 'x' and 'y' in the expression, for this, we can use distributive property of multiplication that says,
Using the distributive property of multiplication:
Now, we know that 
We get, 
Therefore, =
.
(iv) We have, 
, we need to substitute the value of 'x' and 'y' in the expression, we get:
Again, we can use distributive property of multiplication that says,
So,
since, 
we get,
Therefore,
Answer:
7 is the closest estimate for the side length cuz 7 (length) x 7 (width) = 49 squared.
