Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :

Here, a = -9, b = 2 and c =3
Put the values,

So, the solution are -0.47 and 0.69.
3 probably will be the gcf of it.... or maybe 3x^3 y^3 z
Not sure tho
Answer:
None of them are correct because the circumference formula is 2pir
A is simple radical form is 55
