Answer:
112
Step-by-step explanation:
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>
Answer:
54.872
Step-by-step explanation:
volume of a cube = s³
where s = side length
side length given here is 3.8
so volume = 3.8³ = 54.872
Answer:
1) x = 31
2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).
Step-by-step explanation:
1) Since both angles add up to be a supplementary,
→ equation 1 + equation 2 = 180
→ (3x + 25) + (2x) = 180
Solving by applying algebra will give the answer "x = 31".
Hope this helps!
