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:
7√3
Step-by-step explanation:
To simplify a square root, look for some of its factors. You are especially looking for factors that are square numbers, or sometimes factors that repeat (repeating factors give you a square number).
√147
=√3·49 Remember 49 is a square number, you can take out its square root.
=7√3 Simplified.
You might also end up with these factors instead.
√147
=√3·7·7 Two same factors mean a square number you can take out.
=7√3 Simplified form.

Answer:
Answer: It´s correlated. Step-by-step explanation: The graph shows that the height of the tree increases as time passes, meaning that the more time that a three has been planted the more height it has, so there´s a direct correlation between the time passing and the height of the tree.
Answer:
S = 5y + 4
Step-by-step explanation:
f is Sara's father, y is Sara, b is Sara's brother and S is sum
3y = f
b = y + 4
S = f + y + b
= 3y + y + y + 4
= 5y + 4
Hope this helps!
