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

LM

KL = LM

KL , substitute :

KL

KL

KL

let's also find LM just for fun

LM , substitute again:

LM

LM

LM

this proves that KL = LM

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

mrb

the answer is d. (1.2, -4.7) on edgn

hope this !
