Answer:
No real solutions
Step-by-step explanation:
Divide both sides by 3
3x^3/3=-54/3
x^2=-18
Take square root
x=±√−18
Answer:

Step-by-step explanation:
Iliana's math grade increased from 65 to 86.
So, the percentage increase in the her math grade will be
% (Approximate)
Now, Fiona's math grade increased from 70 to 80.
Hence, the percentage increase in her math grade will be
% (Approximate)

(32.31 - 14.28) ≈ 18%
So, it is eighteen percent. (Answer)
Knowing the squareroot of 81 is 9, we can easily know that square root of 83 is close to 9.
9 to the closest tenth is 10.
