x-60 is the length. Multiply you get x2-110x=3000 this is a quadratic equation.

In ∆TUV, Y is the centroid. If TW = 30, what is YW?
nasty-shy [4]
The complete question in the attached figure

we know that
t<span>he centroid is always 2/3 the distance of each median to each vertex
TW=30
TW=TY+YW
TY=(2/3)*30---------> TY=20
then
YW=TW-TY-----------> YW=30-20-----------> YW=10

the answer is 
YW=10</span>

-114=-5x-2(4x+18)<br> ????????
SVETLANKA909090 [29]

Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho)  -114 = -5x -2(4x+18)

-2 . 4x = -8x        +     -2 . 18 = -36        =   -8x-36


Agora soma os números com incógnitas (no caso x)

-114 = - 5x - 8x -36    


Joga a incógnita do outro, tornando positiva

-114 = -13x - 36            

13x -114 = -36


e o 114 do outro lado, ficando positiva também  

13x -114 = -36

13x  = - 36 + 114

13x = 78

x = 78 /13

x= 6


ESPERO TER AJUDADO :)
