Answer:
I can't see anything
Step-by-step explanation:
The coefficient matrix is

Its determinant is then

which is equal to 0.
1. 175m^2
2. 289.7cm^2
3. 42.8in^2
4. 62.4in^2
5. 88ft^2
6. 308.8cm^2
For all of these problems, I used the formula:
SA = Area of the base + 1/2(Perimeter of the Base)(Slant Height)
Work:
A 12-pack of boxes is 4 3-pack of boxes, I found this by dividing 12 by 3.
A 24-pack of boxes is 2 12-pack of boxes, found by dividing 24 by 12.
A 24-pack of boxes is 8 3-pack of boxes, found by dividing 24 by 3 or by multiplying the two previous together (sometimes may not work)
Multiply
$1.09 × 4
That gets you to $4.36, which is less than the price of a 12-pack of boxes.
Then, multiply
$4.39 × 2
That gets you $8.78, which is less than a 24-pack of boxes.
Finally, multiply
$1.09 × 8
That gets you $8.72, which is less than a 24-pack of boxes.
Answer:
The best to buy is the 3-pack of boxes of juice, because it is cheaper when buying multiple of the 3-packs than it is to buy one or more of the 12-pack or 24-pack.
Hope this helps anyone with the question.
