Question

Find QR.
A).12
B).-8
C).9
D).6

Answer 1

D. 6

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 !!!
