Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= ![\[2* [(5 + 2y) + (10 + 4y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%285%20%2B%202y%29%20%2B%20%2810%20%2B%204y%29%5D%5C%5D)
Simplifying,
= ![\[2* [(15+6y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%2815%2B6y%29%5D%5C%5D)
= ![\[(30+12y)\]](https://tex.z-dn.net/?f=%5C%5B%2830%2B12y%29%5C%5D)
Hence the perimeter of the rectangle is given by (30 + 12y)

x= undefined
y= 0
____________
Answer:
It is the 3rd choice. It is 4 times as big as the smaller cylinder
Step-by-step explanation:
V = πr2h
r - radius
h - height
π - pi
= π(3)2(10)
enter into a calucaltor and you get 282.74
= π(6)2(10)
enter into a calucaltor and you get 1130.97
Divide 1130 by 282 and you get about 4
The answer is 3 because its 27/9
