Your factors are (x+7)(x-5)(x+3)
multiply the first 2 to get (x^2 + 2x - 35)(x+3)
Now multiply in the 3rd one
x^3 + 2x^2 - 35x + 3x^2 + 6x - 105 now combine like terms
x^3 + 5x^2 -29x - 105 or A
Which one do you need help with

Step-by-step explanation:
I hope it's right. Sorry if it's not right.
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
= 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
= 16 miles per hour
