−4(3.2−3k)+0.2(9+15k)

Distribute:

=(−4)(3.2)+(−4)(−3k)+(0.2)(9)+(0.2)(15k)

=−12.8+12k+1.8+3k

Combine Like Terms:

=−12.8+12k+1.8+3k

=(12k+3k)+(−12.8+1.8)

=15k+−11

Answer:

I Don't think it is D or A. So it could be B or C.

Step-by-step explanation:

Biodiversity change is caused by a range of drivers. A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. ... Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).

I hope some of this may help. I am sorry so sorry if I'm wrong but i do not think it is D. Hope this helps if not again i'm REALLY sorry.
