Answer:

  • 6) 19
  • 7) 22

Step-by-step explanation:

  • Diagonals of a rectangle are congruent

#6

JL = KM

  • 3x + 4 = 4x - 1
  • 4x - 3x = 4 + 1
  • x = 5

JL = 3*5 + 4 = 19

#7

JL = KM

  • 2x - 6 = 3/2x + 1
  • 2x - 3/2x = 1 + 6
  • 1/2x = 7
  • x = 14

JL = 2*14 - 6 = 22

Answer:

JL = KM

3x + 4 = 4x - 1

4x - 3x = 4+1

X= 5

JL = 3*5 + 4 = 19

JL = KM

2x - 6 = 3/2x + 1

2x - 3/2x = 1 + 6

1/2x = 7

X= 14

JL = 2*14 - 6 = 22
