Answer:
x+15
Step-by-step explanation:
dont question i just know lol
There are 8000 millimeters because 1 liter is also 1000 millimeters
The answer is 60.
The formula for finding the area of a trapezoid or trapezium (UK) is
![A= \frac{1}{2} (base1+base2)(height)](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28base1%2Bbase2%29%28height%29)
Base1 and base2 can be either 8 or 12 and the height is 6.
![A= \frac{1}{2} (8+12)(6)](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20%288%2B12%29%286%29)
Then Solve for parenthesis first.
![A= \frac{1}{2} (20)(6)](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2820%29%286%29)
Then multiply to get the answer.
![A= (10)(6) ](https://tex.z-dn.net/?f=A%3D%20%2810%29%286%29%0A)
