Answer 1

Please Help

Answer 2

:(

Answer 3

@jdoe0001 do you think you'd be able to help me??

Answer 6

I just don't understand it at all, and I have looked at alot of examples but can never get it sadly :(

Answer 7

hmm well using the side-splitter theorem
hmm lemme check

Answer 8

notice that the midsegment in that link
DE is 1/2 of the longer AB

Answer 9

yes

Answer 10

and you have those values thus
we konw that FE = x+5
and that BC = 3x+2

thus \(\bf FE=x+5\qquad BC=3x+2\qquad FE=\cfrac{1}{2}BC\to \cfrac{BC}{2}\quad thus
\\ \quad \\
x+5=\cfrac{3x+2}{2}\)

solve for "x"

Answer 11

shoot okay so you would end up with x=2
am i right??

Answer 12

i don't think i did that correct....

Answer 13

well.. is not 2

Answer 14

okay so i did do that wrong..

Answer 15

so what is x???
