Let's find out!
-5 + x * x + 4.
-5 + x^2 + 4.
-5 + 4 + x^2.
-1 + x^2.
5 + x * x - 4.
5 + x^2 - 4.
5 - 4 + x^2.
1 + x^2
So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.
3^2= 9. And 9 times 0.2 is equal to C. 1.8
<span> 0=4+n over 5
In number form the equation is
</span>

<span>We want to isolate n, so to undue division we multiply, we'll multiply each side by 5 Leaving the equation as
</span>

<span>
Next we'll subtract 20 from each side to isolate n
The equation would now be
</span>

<span>
So the answer is
N=-20</span>
