Answer 2

A. (8)(-4.5)

Step-by-step explanation

The given expression is

`- 4.5 * - 8`

We evaluate this to obtain:

`- 4.5 * - 8 = 36`

For option A

`(8) * - 4.5 = - 36`

For option B

`8 * 4.5 = 36`

For option C,

`- 8 * - 4.5 = 36`

For option D

`(4.5)(8) = 36`

The odd one is option A.

The correct answer is A.
