Statement 1: $$-4≤x+2≤4$$

or $$-6≤x≤2$$. So there are multiple values of $$x$$. Insufficient

Statement 2: $$x=-6$$ or $$6$$. Again multiple values. Insufficient

Combining 1 & 2 the only common value is $$x=-6$$. Sufficient

The answer is C since x<= 2 or x<=-6 from 1st statement and from 2nd x<= +6 or -6. therefore combining x<= -6.
