anyone?

Answer 1

x<=12

Answer 2

is that the final answer?

Answer 3

yup

Answer 4

so how did you solve it

Answer 5

x^3-144x <= 0
x(x^2-144) <=0
x^2-144 <=0
x^2 <=144
x <= sqrt(144)=12

Answer 6

i'm not sure but i think the solution set should include the infinity sign in it..

Answer 7

it can be written as \[(\infty,12] \]
