Need help ASAP!
Should be simple geometry but I’m brainless

x = 6 and KL = 32
First off, you're not brainless, your brain needs practice that's all.
Since L is the midpoint of the line KM, that means KL = LM
KL [tex]= 5x + 2[/tex]
LM [tex]= 9x - 22[/tex]
KL = LM
[tex]5x+2=9x-22\\5x=9x-24\\-4x=-24\\x=\frac{-24}{-4} \\x=6[/tex]
KL [tex]= 5x + 2[/tex], substitute [tex]x[/tex]:
KL [tex]=5(6)+2[/tex]
KL [tex]= 30 + 2[/tex]
KL [tex]= 32[/tex]
let's also find LM just for fun
LM [tex]= 9x-22[/tex], substitute [tex]x[/tex] again:
LM [tex]= 9(6) -22[/tex]
LM [tex]=54-22[/tex]
LM [tex]=32[/tex]
this proves that KL = LM
