Answer:
134.0cm3
Step-by-step explanation:
v=pi r2*h/3
=16 pi*8/3
=134.0 cm3
Vertical angles are equivalent so
7x-4=87
and 4 to both sides to remove the negative numbers, the new equation is
7x=91
Then divide both sides by 7 and you get the answer
1x=13
Makes sense?
Answer:
-3
Step-by-step explanation:
slope = Δy / Δx = -6/2 = -3
X+(4x-20)=180
=>5x-20=180
=>5x=200
=>x=40
Answer:
The coordinates of the vertex are
(-5;-9)
