Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.

Let the empty side equal zero.
Add 3/d-4 and 2/d+2

Then add that to -3d.

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
6.4 months Because 10% of $1,100 is $110
multiply 110 by 6.4 and you get 704
so 6.4 months
