Answer:
The total change that will likely occur in 2 years is mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by mg/L .
It is estimated that the chloride concentration will change mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by mg/L in first year.
The chloride concentration will change mg/L the next year.
The total change that will likely occur in 2 years is
In a mixed fraction - mg/L
X/y=z
if we know x and z
solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y
therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
=?
solve
first factor them
=?
x^2-x+1=?
the poly is x^2-x+1
if we know x and z
solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y
therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
solve
first factor them
x^2-x+1=?
the poly is x^2-x+1
