Let's call your number n. Twice your number is 2n. The product of your number and twice your number (so n multiplied by 2n) is 128.
Set up an equation:
n × 2n = 128
2n² = 128
Divide both sides by 2:
n² = 64
Square root both sides to isolate n:
n = 8
The question asks for half your number, so just half 8:
8 ÷ 2 = 4.
Half your number is 4.
I'd choose C.) and here is why. If I asked someone for directions to a hotel they are going to describe the roads and buildings to me. They might say it is built in an embankment then I know to look for a hotel in an embankment. If this is wrong please let me know so I can research more on the subject.
Metal, metal, nonmetal, metal, nonmetal, nonmetal. For the covalent bonds, it's always between nonmetals. For the ionic, it's a metal and a nonmetal. Hope this helps!
Characteristically, Command Economies are bad when it comes
to a person interested in making a profit; this is because they
typically center on economic equality and do not have economic efficiency. Speaking
in general, in a command economy, the allocation of resources is done by a
Central Planning Committee, and this system usually leads to quite a number of
shortages and/or surpluses in products since the demand/supply can be impulsive.<span> On the other hand, Market Economies are centered on profit-making
and Economic Efficiency.</span>

Essentially, how well resources are distributed among the
public will determine how well people will be rewarded. Let’s take for instance,
a parking lot like downtown; characteristically, a market economy will likely focus
on how to place as many cars as possible in the lot and how to use the space to
its full capacity, while a Command will most likely try to apportion the space
so that (just for example) 3 small, 3 medium and 3 large vehicles are parked (economic
equality).
<span>
<span>Finally, with a market economy, there is likely to
to be less shortages and less surpluses, since it works with the Law of Supply
and Demand in which an equilibrium price will be automatically established
through buying and selling.</span></span>
