Question

Given JK=2x - 2, KL=x -9 and JL = 2x + 8, determine the numerical length of KL.

Answer 1

10 units

Step-by-step explanation:

• JK=2x - 2

,

• KL=x -9

,

• JL = 2x + 8

`\begin{gathered} JL=JK+KL \\ 2x+8=2x-2+x-9 \\ 2x+8=3x-11 \\ 3x-2x=8+11 \\ x=19 \end{gathered}`

Therefore, the numerical length of KL will be:

`\begin{gathered} KL=x-9 \\ =19-9 \\ =10\text{ units} \end{gathered}`
