Answer:
Step-by-step explanation:
Add 1 and subtract 1, so that the expression won't change.
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1
![= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ]](https://tex.z-dn.net/?f=%3D%20%5B%20%28x%5E%7B2%7D-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%29%2B%201%20%5D%20%5B%20%28x%5E%7B2%7D%20-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%20-%201%20%5D)

Answer:
0≥x<4
Step-by-step explanation:
first, let's look at this number line.
there is a closed circle at 0 and an open circle at 4. this means that 0 is included (≤ or ≥) and that 4 is not included (< or >).
these are the endpoints, meaning that in this compound inequality, the numbers next to the symbols are 0 and 4.
x is in the middle of this compound inequality.
0 x 4
now, we have to figure out the symbols in between. i wrote out our choices above for each number. the highlighted portion is greater than or equal to 0 and less than 4, so we can write this compound inequality as the following:
0≥x<4
x is greater than or equal to 0, but less than 4
After 4 atmospheres the diver descends -132 feet because -33*4=-132
