Pls tell me it’s a, b,c, or d. really need it thx

B and C are both correct so idk

Step-by-step explanation:

when you multiply the numbers outside of the choices, both answers in B and C are correct.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
