Answer 1

from the question;

we to find |x| when x = 15 and when x = -15

by definition of absolute value we have

`\lvert x\rvert\text{ = x}`

Thats for every value of x, the absolute value is always positive

Hence,

`\begin{gathered} \text{when x = 15} \\ \lvert15\rvert=\text{ 15} \end{gathered}`

Also

`\begin{gathered} \text{when x = - 15} \\ \lvert-15\rvert\text{ = 15} \end{gathered}`

Therefore the correct answer is

Both values are 15
