.
Answer: The volume of candy is 21π.
Answer:
–4(x + 3) ≤ –2 – 2x
>>.....-4x -12 ≤ -2 -2x
>> -12 +2 ≤ +2x
>> - 10 ≤ 2x
>> -5 ≤ x............>> x >= -5
Step-by-step explanation:

The sum of 5 and 12 is 7 if and only if 5 is a negative integer such that
-5 +12 =7.
Integers are whole numbers which are either negatives or positive normally shown using a number line.
