Final answer:
The expression for JL, which is the sum of JM and LM, is calculated as 7x – 14, by adding the expressions for JM (5x – 8) and LM (2x – 6) together.
Step-by-step explanation:
If JM = 5x – 8 and LM = 2x – 6, the expression that represents JL is found by adding the two expressions together, since JL is the sum of JM and LM. We can denote JL as JM + LM. So, we have:
JL = (JM) + (LM)
= (5x – 8) + (2x – 6)
= 5x + 2x – 8 – 6
= 7x – 14.
Therefore, the expression for JL is 7x – 14.
