Answer:
OD
Step-by-step explanation:
because it gives us error and there's no number
The answer is D. 2^3 is 8.
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 .
56.25 minutes
Explanation: to find how long it takes to run one mile, divide 50 minutes by 8 miles.
50/8 = 6.25
Then you can multiply 6.25 by 9 to find the answer.
9 x 6.25 = 56.25 minutes
