PLEASE HELP!! Will mark brainliest, i’m struggling. Please find PR.

PR = 15

Step-by-step explanation:

            PR = PQ + QR

   10x - 45 = 3 + x + 6  {Combine like terms}

   10x - 45 = 9 + x             {Subtract 'x' from both sides}

10x - x - 45 = 9

      9x - 45 = 9                  {Add 45 to both sides}

             9x  = 9 +45

             9x = 54

               x = 54/9

x = 6

PR = 10x - 45

     = 10*6 - 45

     = 60 - 45

PR = 15

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! (:
