First, let's find all the factors of 81:
81/3=27
27/3=9
9/3=3
3/1=1
So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).
This means we can write down 81 as 3*3*3*3 or

- which is the answer to the question! (three to the power of 4)
Divide the total spent by the total feet:
$398.40 / 1000 = 0.3984 per foot.
Round the answer as needed.
Answer:

Step-by-step explanation:
Notice that in the second equation, the coefficient of
is
times greater than in the first. Therefore, by making the coefficient of
in the second equation
times greater than in the first, it's impossible to only isolate one variable.
Therefore, when
, there are no solutions to this system.
The median is 10.5 because its the middle line in the box and all you have to do is look at it and you can see it
Answer:
F. 6 x 22
Step-by-step explanation:
- 6 has more than two factors ( 1, 6, 2, 3), which makes it a composite number.
- 22 has more than two factors (1, 22, 2, 11), which makes it a composite number.
- Therefore, F is the correct answer.
