Answer:
[tex]\text{B. }26}[/tex]
Step-by-step explanation:
Since [tex]\overline{PN}[/tex] and [tex]\overline{PQ}[/tex] are equal, we can set them equal to each other:
[tex]7x+5=10x-4,\\9=3x,\\x=3[/tex]
Substitute [tex]x=3[/tex] to solve for [tex]\overline{PQ}[/tex]:
[tex]\overline{PQ}=10(3)-4=\boxed{\text{B. }26}}[/tex]
