Find QR. A).12 B).-8 C).9 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 !!!
