Answer:
D. 6
Step-by-step explanation:
Let's first find x :-
[tex]\sf 3 + 2x + 22 = x + 17[/tex]
- [tex]\sf 2x + 25 = x + 17[/tex]
- [tex]\sf 2x - x = 17 - 25[/tex]
- [tex]\sf x = - 8[/tex]
Now that we found x, let's find QR :-
QR = 2x + 22
- [tex]\sf QR = 2( - 8) + 22[/tex]
- [tex] \sf - 16 + 22[/tex]
- [tex]\sf 6[/tex]
Therefore, QR = 6 !!!
