Your answer is going to be the first one: 3^2
Answer:
The length of each side of the 9 in
Step-by-step explanation:
The volume of the gift box is 972 in. The height of the gift box is 12 inches
and the area of the base is 81 in².
We want to determine the length of each side of the square base if the base shape is a square.
Recall that, the area of a square is
![{l}^{2}](https://tex.z-dn.net/?f=%20%7Bl%7D%5E%7B2%7D%20)
It was given that, the area of this base is 81 in²
![{l}^{2} = 81](https://tex.z-dn.net/?f=%20%7Bl%7D%5E%7B2%7D%20%20%3D%2081)
Take positive square root:
![l = \sqrt{81} = 9in](https://tex.z-dn.net/?f=l%20%3D%20%20%5Csqrt%7B81%7D%20%20%3D%209in)
2/3x + 4=6. Is that what you mean?
A "roster" here is essentially a version of the set with all of elements listed out. Here, those elements are all of the odd numbers between 20 and 30, so our list would be
{21, 23, 25, 27, 29}
