As written, it is interpreted to mean 14·22·350·x = 107800x.
_____
Often such an expression written here on Brainly is expected to be interpreted as an exponential expression: 
Keywords:
<em>equation, operations, equivalent, binomial, square root
</em>
For this case we have an equation in which we must apply operations to rewrite it in an equivalent way. We must start by raising both sides of the equation to the square. Thus, we eliminate the square root of the left side of equality and finally solve the binomial of the right side of equality.
So we have:

By definition:

Thus,
is equivalent to 
Answer:

Option D
im am pretty sure it is b.sometimes because an equation can have more then one answer
Answer:
A. t(x) = 450 - 0.06x
Step-by-step explanation:
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
