The order is III, II, I, IV
Answer:
Step-by-step explanation:
Factor it by first setting it equal to 0:
Now subtract 9 from both sides:
Divide both sides by 4:
Then take the square root of both sides:
x = ±
, which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,
x = ±
is an equivalent radicand, we can now replace -1 with its imaginary counterpart:
x = ±
Each one of the elements in the radicand are perfect squares, so we simplify as follows:
x = ±
And there you go!
Answer:
<h2>-4</h2>
Step-by-step explanation:

Answer:
18
Step-by-step explanation:
Hello,
In order to solve for x, we need to isolate the variable on one side of the equation.
To do this, we subtract 450 from both sides of the equation, and this will give you:
28.75x = 517.5
As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.
x = 18
Hope this helps!
