Find QR. <br> A).12<br> B).-8<br> C).9<br> D).6
mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

\sf 3 + 2x + 22 = x + 17

  • \sf 2x + 25 = x + 17
  • \sf 2x - x = 17 - 25
  • \sf x =  - 8

Now that we found x, let's find QR :-

QR = 2x + 22

  • \sf QR = 2( - 8) + 22
  • \sf - 16 + 22
  • \sf 6

Therefore, QR = 6 !!!
