Perimeter = 2w + 2l
2(8x+2) + 2(6x + 6)
Use distributive property
16x + 4 + 12x + 12
Combine like terms
28x + 16
Solution: 28x + 16

Answer:
6π cm³
Step-by-step explanation:
V = Ah ( A is the base area and h the height ), then
3πh = 18π ( divide both sides by 3π )
h = = 6
Then the height of the smaller cylinder = 6 - 3 = 3 cm
V = 3π × 3 = 9π cm³ ← volume of smaller can

Answer:
450 ml.
Step-by-step explanation:
Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.
We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:
We are also told that Alla drinks 50% more than Balla. We can represent this information as:
From equation (1) we will get,
Upon substituting this value in equation (2) we will get,

Upon distributing 1.5 to right hand side of the equation we will get,

Upon adding 1.5x to both sides of equation we will get,


Let us divide both sides of our equation by 2.5.

Therefore, Alla drank 450 ml of water.
The answer is B! Good luck!
