13.2 first look at the 2 if is lower then the number five so u round down to 0 the decimal stays there so it's no 13.0 now u do the same to the 13 only u round up since its higher so u round it up to 20 and ur answer should be 20.0
Solution:
we have been asked to find the solution of the equation
It can be solved using factoring as below:
![x^6 + 6x^3 + 5 = 0\\\\substitute, x^3=y\\\\y^2+6y+5=0\\\\y^2+5y+y+5=0\\\\y(y+5)+1(y+5)=0\\\\(y+5)(y+1)=0\\\\y=-1,-5\\\\\text{substitute back }y=x^3\\\\x^3=-1,-5\\\\x=-1,\sqrt[3]{-5} \\\\\text{These are the only real solutions}\\](https://tex.z-dn.net/?f=x%5E6%20%2B%206x%5E3%20%2B%205%20%3D%200%5C%5C%5C%5Csubstitute%2C%20x%5E3%3Dy%5C%5C%5C%5Cy%5E2%2B6y%2B5%3D0%5C%5C%5C%5Cy%5E2%2B5y%2By%2B5%3D0%5C%5C%5C%5Cy%28y%2B5%29%2B1%28y%2B5%29%3D0%5C%5C%5C%5C%28y%2B5%29%28y%2B1%29%3D0%5C%5C%5C%5Cy%3D-1%2C-5%5C%5C%5C%5C%5Ctext%7Bsubstitute%20back%20%7Dy%3Dx%5E3%5C%5C%5C%5Cx%5E3%3D-1%2C-5%5C%5C%5C%5Cx%3D-1%2C%5Csqrt%5B3%5D%7B-5%7D%20%5C%5C%5C%5C%5Ctext%7BThese%20are%20the%20only%20real%20solutions%7D%5C%5C)

Answer: option d) (1/16) (42 - x)
Explanation:
1) You forgot to include the table.
This is the table:
Rate time distance
(mi / min) (min) (mi)
up the hill 1/12 x (1/12)x
down the hill 1/16 42-x ?
2) You also forgot to include the set of answerchoices. This is it:
a) x
b) -x
c) 42 - x
d) (1/16) (42-x)
3) Solution:
The missing value is the distance of the trip down the hill.
The distance is the rate times the time, i.e.:
distance = rate * time
the rate is given as 1/16, and the time is given as 42 - x, so the distance is:
distance = (1/16) (42 - x), which is the answer.
