Answer:
(6x-11) / (x-10)
Explanation:
Here we're adding together two functions with the same denominator (x-10). All that is necessary now is to add together the numerators of these functions. We get, as the numerator of the sum, 4x-3 plus 2x-8, or 6x-11.
Thus, the desired sum is
6x-11
----------- This is the first answer choice.
x - 10
