I would go with cylinders cause it's a tube it doesn't any sharp points or angles like the other choices. hope this helps.
Answer:
x = 8
y = 1
Step-by-step explanation:
First you want to substitute y in for 1 to get
2x + 4 = 20
Then subtract four to both sides to get
2x = 16
Then divide 2 by 16 to get
x = 8
and then plug the 8 into the original equation
2(8) + 4y = 20
And then solve for y!
This is the division for your problem hope this helps!
