V=4/3 πr^3would be the formula
Answer:
x = 18
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+x+x=54
(x+x+x)=54(Combine Like Terms)
3x=54
3x=54
Step 2: Divide both sides by 3.
3x 3
=
54
3
x=18

Answer:
Option A is correct.
Solution for the given equation is, 
Step-by-step explanation:
Given that : 
Let 
then our equation become;
.....[1]
A quadratic equation is of the form:
.....[2] where a, b and c are coefficient and the solution is given by;
Comparing equation [1] and [2] we get;
a = 2 b = -1 and c =-1
then;
Simplify:
or
or
and 
Simplify:
y = 1 and 
Substitute y = cos x we have;
⇒
and
⇒ 
The solution set: 
Therefore, the solution for the given equation is,
