Answer:
Step-by-step explanation:
A
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>

Learn this and it can answer all ur percent problems
percent formula : is/of = %/100
36 is 75% of what number...
is = 36
% = 75
of = x.....because that is what u are looking for.
now sub into the percent formula
is/of = %/100
36/x = 75/100
cross multiply because this is a proportion
75x = 36(100)
75x = 3600
x = 3600/75
x = 48
so 36 is 75% of 48
