27x^3 - 12x factors into
3(9x^3 - 4x) a common factor of three has been taken out.
3x(9x^2 - 4) a common factor of x has been taken out. 3x is not a linear factor.
9x^2 - 4 factors by means of the difference of squares
3x(3x - 2)(3x + 2)
The two linear factors are 3x - 2 and 3x + 2
(2/3)*(c-18)=7 <em>(Multiply terms on both sides of equation by 3)</em>
2(c-18)=21
2c-36=21
2c=57
c=57/2
c=28.5
Answer:
Step-by-step explanation:
Given:
The expression to evaluate is given as:
The value of 'x' is 4.
Plug in 4 for 'x' in the above expression and simplify. This gives,
Therefore, the value of the given expression for 'x' equal to 4 is 0.
