It’s b
Step-by-step explanation:
Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !
Answer whats the question?
Step-by-step explanation:
Answer:
The value of y is 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides
I choice
Multiply the equation A by -18/4 both sides
![(-18/4)[4x+3y]=6*(-18/4)](https://tex.z-dn.net/?f=%28-18%2F4%29%5B4x%2B3y%5D%3D6%2A%28-18%2F4%29)
------> equation C
Adds equation B and equation C
