Answer:
A
Step-by-step explanation:
multiply 9 by 12 to get the surface area of the end of the rectangle.
you should get 108.
multiply 12 by 9 to get the surface area of the side.
you should get 135.
multiply 12 by 15 to get the surface area of the bottom.
you should get 180.
 then add all your answers and multiply by 2  this will give you the total surface area and you will find that the answer is A.
 
        
             
        
        
        
Answer:
3/4, 
12/16,
 18/24,
24/32
30/40
...So on, So on...
Step-by-step explanation:
Any fraction that you multiply by the same number on the bottom and on top.
So, multiply by two, what you do to the top do to the bottom. = 12/16
Multiply by three = 18/24
So on, so on.
Or you can reduce, 6/8 divide by 2 = 3/4.

Answer:
 = - 5n - 2
 = - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
 = a₁ + (n - 1)d
 = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
 = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
 = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
