$\bf \cfrac{7y-x}{z}~~ \begin{cases} x=9\\ y=5\\ z=4 \end{cases}\implies \cfrac{7(5)-9}{4}\implies \cfrac{35-9}{4}\implies \cfrac{26}{4}\implies \cfrac{13}{2}\implies 6\frac{1}{2}$

PQ // BC

then

Angle P = Angle B, A is common angle the two triangles are similar

AP/AB = AQ/AC

8/18 = 12/ AC

AC = 12 * 18/8 = 27 (your ans: D)

AQ + QC = AC

QC = AC - AQ = 27 - 12 = 15 (if it was required)

tan60 = y/8

y = s tan60 = 8sqrt(3) (B)

Next time, post each question separately.
