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
Answer:
199.5
Step-by-step explanation:
3 is not greater than 5
3c^2 - 8c + 5 = 3c^2 - 3c - 5c + 5 = 3c(c - 1) - 5(c - 1) = (3c - 5)(c - 1)
