Answer:
The answer to your question is 
, because the directions says to give the answer in factor form.
Step-by-step explanation:
Factor like terms (x - 7)(x + 1)²
Simplify
![\frac{(x+1)^{2}[3(x - 7) - 2(x+1)]}{(x-7)^{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B1%29%5E%7B2%7D%5B3%28x%20-%207%29%20-%202%28x%2B1%29%5D%7D%7B%28x-7%29%5E%7B3%7D%7D)

Answer:
- boat speed: 17.25 mph
- current: 2.5 mph
Step-by-step explanation:
Upstream, the speed of the current (c) subtracts from the speed of the boat (b) to give the net speed. Downstream, the speed of the current adds. We can make use of the relation ...
speed = distance/time
b-c = 29.5/2 = 14.75 . . . . . miles/hour
b+c = 59.25/3 = 19.75 . . . .miles/hour
Subtracting the first equation from the second, we get ...
(b+c) -(b-c) = 19.75 -14.75
2c = 5
c = 2.5
Then either equation can be used to find b:
b = 14.75 +c = 17.25
The speed of the boat in still water is 17.25 miles per hour; the speed of the current is 2.5 miles per hour.
Think it should just be A B D C not sure though, try it
