In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .

Answer:
9 2/7
Step-by-step explanation:
4 1/3=13/3
2 1/7=15/7
13/3*15/7= 195/21
=9 6/21
=9 2/7
Answer:
−(d+1)>3
Step 1: Simplify both sides of the inequality.
−d−1>3
Step 2: Add 1 to both sides.
−d−1+1>3+1
−d>4
Step 3: Divide both sides by -1.
> 
d < -4
