Answer:15x+7
Step-by-step explanation:
First you would see that the -(-10x+6) would turn into 10x+6 meaning that the whole equation would turn into 5x+1+10x+6. Then add the x numbers together and the whole numbers separate. So now your answer should be 15x+7

Option B is right.
Answer:
D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.

Therefore, the only correct option is Option D.
