x = 57

x = 13

Answer 1

setup a proportion, taking ratios of medians and sides

Answer 2

What is the answer x=15

Answer 3

how did u get 15, did u take a proportion ?

Answer 4

i dont know how to do this problem

Answer 5

ok np, do u knw wat a proportion is ?

Answer 6

no

Answer 7

wat about "ratio"

Answer 8

Answer 15

ok

Answer 16

look at triangle ABC

Answer 17

BD is called median

Answer 18

cuz BD divides the triangle into two equal parts

Answer 19

now look at the triangle EFG and tell me whats the median

Answer 20

3

Answer 21

my i knw why do u think 3 is median

Answer 22

3 can solve for x and 3 plus 2 wpuld be 5

Answer 23

*may

Answer 24

forget it

Answer 25

look at triangle EFG, can u locate the line segment FH ?

Answer 26

yes

Answer 27

thats the median for that triangle, cuz it is dividing that triangle into two equal parts

Answer 28

so whast the answer

Answer 29

you tell me answer

Answer 30

15

Answer 31

show me how u got 15

Answer 32

im guessin
i dont know how to do this

Answer 33

then you should know how to do this

Answer 34

can you just tell me

Answer 35

no

Answer 36

a hint

Answer 37

5/11=x+2/2x+7

Answer 38

thats correct. cross multiply and solve, what u waiting for ?

Answer 39

thats as far as i can get

Answer 40

next steps :-

1. cross multiply
2. solve x

Answer 41

what do i cross multiply

Answer 42

http://www.mathsisfun.com/algebra/cross-multiply.html

Answer 43

that site explains better "how to cross multiply"

Answer 44

\(\large \frac{5}{11}= \frac{x+2}{2x+7} \)

Answer 45

\(5(2x+7) = 11(x+2)\)

can u take it from here ?

Answer 46

Determine whether ΔABC ~ ΔFED. If they are similar, what postulate or theorem proves their similarity?

Answer 47

you finished with the previous problem ?

Answer 48

yep

Answer 49

good :) wat u got for x ?

Answer 50

Side-Angle-Side Similarity Postulate

Side-Side-Side Similarity Postulate

Similarity cannot be determined.

Angle-Angle Similarity Postulate

Answer 51

thise are the answers

Answer 52

hmm i asked u a q above

Answer 53

theres no x

Answer 54

im asking about the previous problem we worked so far
