To determine the maximum and minimum temperatures at which nitrogen remains a liquid, use the equation |x - (-333.32)| = 12.78, where x is equal to the maximum and minimum temperatures. Using this equation, the maximum temperature is -320.54 degrees Fahrenheit while the minimum is -346.10 degrees Fahrenheit.
Answer: 54 ft²
Step-by-step explanation:
Area of a kite is calculated by the formula:
= (Length * Height) / 2
Length = 6 + 6 = 12 ft
Height = 9 ft
Area = (12 * 9) / 2
= 108 / 2
= 54 ft²
Answer:
43.98
Step-by-step explanation:
Combine like terms.
Since 7x and 6x both have a variable of x, you can combine them.

After that, you are left with:

You also have two numbers without variables; 11 and 3. You can also combine those.

So, your final answer would be:
