Helium is being pumped into a sheridan balloon at a rate of 5 cubic feet per second. how fast is the radius increasing after 2 minutes? v=(4/3)(pi)r^3

How are the solutions for |x +4|< -2 and |x +4| < 2 different? a they are not different, because the inequality is an absolute valueb the first inequality has no solution because absolute value cannot be negativec for one the solution is benveen two numbers. for the other, the solution is outside of the twonumbersd. for one the solution is a range of positive numbers, for the other, the solution is a range of negativenumbers
