Yes you can and it is negative because if you think about it, the answer to the 3rd power is your original question, so for example, -8 would equal to the answer times itself 3 times
now ask yourself, does 2 times itself 3 times = to -8
or -2 times itself 3 times = to -8
X should be 33 because its a z angle
Answer:
4.0.
Step-by-step explanation:
In sample 1, you do 0.65/1.3 which gets you to 0.5, so then you do the same to the bottom which you also have to divide by 1.3, and 5.2/1.3 is 4.0 or 4.
X+9 is the same as x+9=0. You subtract 9 from both sides to get x=-9.
The variance would be 1213.89
i hope this helps :)
