The answer is 2.7
I’m not an expert at this but i did some research so I hope I can help
It’s 2.7 because the formula for calculating density is to divide the mass by the volume and in you do that for each of them you get 2.7 every time
Answer: The value of x =2 units.
Explanation:
Since we have given that
AD= CD
BE= EA
So, we get that D and E are the mid-points of AC and AB respectively.
So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

So, we put the value of DE and BC ,

Hence, the value of x =2 units.
Answer:
4 Can I have brainiest me trying to level up
Step-by-step explanation:
Let's make the parenthesis go bye
8-4
so it would be 4
1.)
Between year 0 and year 1, we went from $50 to $55.
$55/$50 = 1.1
The price increased by 10% from year 0 to year 1.
Between year 2 and year 1, we went from $55 to $60.50.
$60.50/$55 = 1.1
The price also increased by 10% from year 1 to year 2. If we investigate this for each year, we will see that the price increases consistently by 10% every year.
The sequence can be written as an = 50·(1.1)ⁿ
2.) To determine the price in year 6, we can use the sequence formula we established already.
a6 = 50·(1.1)⁶ = $88.58
The price of the tickets in year 6 will be $88.58.
5x(x) + (5x)(4) + (-2)(x) + (-2)(4)=
5x^2 + 20x - 2x - 8=
5x^2 + 18x -8
