It’s AE, CG, EF, and GF. Hope this helps
With ellipse the equation to find c or the distance from the center to the foci is c^2 = a^2 - b^2. So if you plug those numbers in you get:
c^2 = 25 - 9
c^2 = 16
c = 4
The distance from the center to each foci is 4
For a string length of 1 there are 2 possible strings (2^1)
for a string length of 2 there are 4 possible strings (2^2)
for a string length of 3 there are 8 possible strings (2^3)
So, for string length of 7 there are 128 possible strings (2^7)
You find it by looking for the key words "points per week"
