• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Expression : $4x-5$
$4x-5$ can be written as $x+x+x+x-1-1-1-1-1$.

So, to represent $x+x+x+x-1-1-1-1-1$, we need 4 tiles of this type where each tile will represent $x$ and 5 tiles of this type where each tile will represent − 1.


Option A has 4 and 5 . So, it is the correct answer.

Option B has 4 and 4 . So, it is incorrect.

Option C has 3 and 5 . So, it is incorrect.

Option D has 4 and 3 . So, it is incorrect.
