Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant
So this question is arithmetic because it keep minus by 7
from 19 - 7 = 12
12 - 7 = 5
5 - 7 = -2
so common difference is -7
or you can check with arithmetic formular as
= 
+ (n−1)d
I will just put in the 4th term which is -2 and n will equal to 4
and is the 1st term which is 19
-2 = 19 + (4−1)d
-2 - 19 = 3d
d = 
d = -7

Answer:
-4x(x +3)
Step-by-step explanation:
Factor out common factors from both terms.
Divide -4 & x from both terms.
(-4x²)/(-4x) = x
(-12x)/(-4x) = 3
x + 3 is the remainder, so keep together.
-4x(x + 3) is your answer

The amount that will be saved yearly oh the utility bills will be $65 each year.
<h3>How to calculate the amount of utility saved</h3>
From the information given, the cost per load on hot wash is given as 71 cents per load and the cost of warm wash is given as 25 cents per load.
Therefore, the yearly cost for hot wash will be:
= 71 cents × 365
= 25915 cents
In this case, she cuts down the amount of laundry that she does in hot water to one-half will be:
= 25915 cents × (3/4 - 1/2)
= $259.15 × 0.25
= $65
In conclusion, the correct option is $65.

No, you do not have enough flour. To solve, you would need to substitute 5 for b, and 2 * 5=10. Since you only have 8 cups of flour, you do not have enough.
