Answer:
Step-by-step explanation:
x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or
x = plus or minus i*2√30
So the correct answer choice here is "None of the above."

The answer is 20.
Solution for 5 is what percent of 25:
5: 25*100 =
(5*100): 25 =
500: 25 = 20
Now we have: 5 is what percent of 25 = 20
Question: 5 is what percent of 25?
Percentage solution with steps:
Step 1: We make the assumption that 25 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=25$100%=25.
Step 4: In the same vein, $x\%=5$x%=5.
Step 5: This gives us a pair of simple equations:
$100\%=25(1)$100%=25(1).
$x\%=5(2)$x%=5(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{25}{5}$
100%
x%=
25
5
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{5}{25}$
x%
100%=
5
25
$\Rightarrow x=20\%$⇒x=20%
Therefore, $5$5 is $20\%$20% of $25
Hope this helps!
