Here, as I can see, you are adding fractions, and making sure you have a common denominator.
12) is correct
13) is correct
You got a common denominator, and added them up! Great job! <span />
<span>Let the major axis = 2a , and the minor axis = 2b
∴ a = 26/2 = 13 and b = 24/2 = 12
and the equation of foci:
c² = a² - b²
= 13² - 12² = 169 - 144 = 25
∴ c = √25 = 5
∴ The distance between the foci = 2 * 5 = 10
