<u>Answer:</u>

<u>Explanation:</u>
let the number be x, now we are given that four times the cube of a number which means four multiplied by the cube of number
i.e 4 multiplied by
is less than the difference of 40 and the number x i.e 40 - x
x is for sure less than 40 as
is less than the difference between 40 and x so if we write x - 40 then we will obtain negative value which will be greater than
.
So, the inequality obtained can be written as 
Answer:
No, they are not.
