If you're trying to make an inequality, it would be:
30 - 4x > -10.
Answer:
Only 
is a perfect cube.
Step-by-step explanation:
is not a perfect cube because 8 is not a multiple of 3.
Now, is a perfect cube since 24 is a multiple of 3.
So, can be expressed as
Again, 
is not a perfect cube as 28 is not a multiple of 3.
And also 
is not a perfect cube as 64 is not a multiple of 3.
Therefore, only is a perfect cube. (Answer)
Answer: he should add 3
Step-by-step explanation: he should add 3 because then you have 4x=12 and that simplifies to x=3
Your answer is Diverge. To tell whether a series is divergent or convergent, you must look at the rate (the number it is being multiplied by) for the series. If the rate is less than 1, then it would be convergent, meaning it does have a sum. If the rate is greater than 1, then that means it does not have a sum and never will. These series will diverge. Now your rate in this problem is 3 and 3 is greater than 1, so it diverges.
