Answer:
Option C. 2x + 20 / x² + 6x – 40
Step-by-step explanation:
f(x) = x + 16 / x² + 6x – 40
g(x) = 1 / x + 10
To find f(x) + g(x), please refer to the attached photo.
Take 20 and divide it by 4 and you get 5mm squared .
There are four sides so take the total which is 20 mm and divide it by the sides to get one side.
Answer is 5mm squared
