Answer:
centroid divides median into the ratio 2:1 then
PC/CY=9/x=2/1
x=4.5
then the total length PY = 9+4.5=13.5
Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10(x−2)=−20
(10)(x)+(10)(−2)=−20(Distribute)
10x+−20=−20
10x−20=−20
Step 2: Add 20 to both sides.
10x−20+20=−20+20
10x=0
Step 3: Divide both sides by 10.
10x/10 = 0/10
