Answer:
JL = 12.5
Step-by-step explanation:
Therefore, by geometric mean property:
JL = JM +ML
JL = 8 + 4.5
If a+b= 2+11 then your sum will be 13.
heres an example...
If you have eleven dollars and I give you 2 more you can simply count up 2 more from 11 leaving you at 13.
you're welcome.
Y is 5! Good Luck Fam
