Answer:
10x.
Step-by-step explanation:
It is given that,
JK = 3x
LM = 12x
JM = 25x
Let as consider the line as shown in the below figure.
From the figure it is clear that,
Therefore, the length of KL is 10x.
54 percent
You add the two together to get 39, then divide 21 by 39. This gives you 0.538, which turns into 54%
C. 8 - 2x = 5x - 2 is the anwser
3-2y-8x is it's most simplified form I think.
