Question

When x = 5, the value of the expression –2(x – 10) is
–21
–9
9
19

Answer 1

If you plug in 5 for x in the expression then you will get 10.

Answer 2

If we evaluate the given expression for x = 5, we have 10 as a result.

Explanation:

The given expression is

`-2(x-10)`

So, if
`x=5`, we just have to replace this value in the expression

`-2(x-10)\\-2(5-10)`

Now, we solve first the difference inside the parenthesis, and then we multiplied that difference with -2, as follows

`-2(5-10)\\-2(-5)=10`

Therefore, the expression when
`x=5` is equal to 10. So, the answer should be "none of the above".
