0
2d + 8e
2d - 2e
32d + 8e

Answer 1

Option C is correct.

2d -2e

Explanation:

Simplify:
`17d-5e + 3e -15d`

Like terms are those terms which have same variable to the same power.

Combine like terms of variable d first;

`(17d-15d)-5e + 3e`

Simplify:

`2d-5e + 3e`

Now, combine like terms of variable e we have;

`2d-2e`

therefore, the simplified form of
`17d-5e + 3e -15d` is, 2d - 2e
