Answer:
Not an arithmetic sequence
Step-by-step explanation:
For the sequence to be arithmetic there must be a common difference between consecutive terms.
- 7 - (- 3) = - 7 + 3 = - 4
- 10 - (- 7) = - 10 + 7 = - 3
- 14 - (- 10) = - 14 + 10 = - 4
The differences are not common , hence not an arithmetic sequence
Answer:
13 cases
Step-by-step explanation:
we know that
You have 1 case of soap bars
There are 150 bars in a case
You use 300 bars of soap per day ----> 2 cases per day
using proportion
Find how many cases do you need to order to have enough for 7 days
Let
x ----->the number of cases
2/1=x/7
x=2*7=14 cases
but remember that you have 1 case
so
you needed 14-1=13 cases
The volume would be x^2-56+56 times the square root of 11
You can write it without exponent
3x*3x or 9x*x
