Question

Which expressions represent the width of the door in the diagram? And please show how you got the answer because it’s a two-part thing?

Answer 1

A.
`(3x + 6) - x - x`.

Explanation:

In the diagram given, the door is located in the middle of the length of the diagram.

The length of the diagram =
`3x + 6`

The width of the door is part of the
`3x + 6`.

x and x, are the remaining part of
`3x + 6`.

To get the width of the door, x, and x, needs to be subtracted from
`3x + 6`.

Therefore, the width of the door =
`(3x + 6) - x - x`.
