Rom4ik [11]

Answer:

1. no solutions

2. one solution

Step-by-step explanation:

1. -4(5-3x)=12x+20

-20+12x=12x+20

-40+12x=12x

-40=0?????

So no solutions.

2. 3x+7(x+1)=2(6x+5)+2

3x+7x+7=12x+10+2

10x+7=12x+12

-2x+7=12

-2x=5

x=-5/2

So one solution.

The centroid splits the median in a 2:1 ratio from vertex to side.
The median bisects the side it is drawn to.

$QR=(1/2)(JQ)=(1/2)(16)=8 \\ \\ LM=(3)(QM)=(3)(6)=18 \\ \\ KQ=(2/3)(KP)=(2/3)(18)=12$
