Question 1 (4 points)

Answer 1

Answer:

24.5

Step-by-step explanation:

Because the figure is a parallelogram, the opposite sides are equal in length.

     1. Set the equations equal to each other:

     JK = LM ⇒ 7x = 3x+14

     2. Subtract 3x from both sides

      7x = 3x+14

    - 3x  - 3x    

    ___________

     4x = 14

     3. Divide both sides by 4

     (1/4)4x = (1/4)14 ⇒ x = 3.5

     4. Plug the value of x into the equation of JK

     JK = 7x ⇒ JK = 7 (3.5)

     5. Multiply

     JK = 24.5
