Answer:
Option B. -j = -h/-k is not correct
Step-by-step explanation:
As from the given scenario both the negative signs will be cancelled out giving positive j : -h/-k = -j
First option has: -j = -h/k In this case also the negative sign from both sides would be cancelled out.
Second option has: -h/-k = -j In this case negative signs cannot be cancelled out.
Third option has: h/-k = -j , negative sign would be cancelled from both sides.
Fourth option has: h/k = j , no negative sign on either side.

Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ 
= 
∴ x = 3
∴ The value of x is 3
