Write a simplified expression for the length of QR.
HELP ME PLASE

Answer/Step-by-step explanation:

Length of AC:

Given that AB = x + 2, and BC = 7x - 3, therefore,

(segment addition postulate)

Simply the expression for the length of segment AC

Collect like terms

Length of QR:

Given that PQ = 8y + 5, and PR = 13y + 25, therefore,

QR = (13y + 25) - (8y + 5) (PQ + QR = PR)

Simplify the expression to for the length of segment QR

QR = 13y + 25 - 8y - 5

Collect like terms

QR = 13y - 8y + 25 - 5

QR = 5y + 20

18*2 = 36 which is a perfect square so n could have a factor 2
if we use 34^2   we have 18*2 * 34^2 =  41616  whose square root is 204

so n = 2*34  = 68 is one possibility but Im not sure if that is the least possible integer value.

what we need is a perfect square which is also divisible by 34.
