Answer 1

D

Explanation:

answer on edge

Answer 2

`8x+4y-2z-8z^2`

Explanation:

Given

`(8x+3z-8z^2)+(4y-5z)`

Required

Write an expression that shows their sum

`(8x+3z-8z^2)+(4y-5z)`

Open Brackets

`8x+3z-8z^2+4y-5z`

Collect Like Terms

`8x+3z-5z-8z^2+4y`

`8x-2z-8z^2+4y`

Reorder the polynomial

`8x+4y-2z-8z^2`

Hence,
`8x+4y-2z-8z^2` is equivalent to
`(8x+3z-8z^2)+(4y-5z)`
