Answer:
A. 14x14x28
B. The maximum volume is 5488 cuibic inches
Step-by-step explanation:
The problem states that the box has square ends, so you can express volume with:

Using the restriction stated in the problem to get another equation you can substitute in the one above:

Substituting <em>y</em> whit this equation gives:

Now find the limit of <em>x</em>:

Find the length:

You can now calculate the maximum volume:

Answer:
1.25b
Step by step explanation:
Step-by-step explanation:
(x²-1)(x+1)≥0
As it has two multiples,
Therefore,
Either,
x²-1≥0
x²≥0+1
x²≥1
x≤√1
x≤1
Or,
x+1≥0
x≥-1
