Answer:
When heated calcium carbonate forms calcium oxide and carbon dioxide.
Answer:
Step-by-step explanation:
The given function is
To find k(-5), we put x=-5 into the given function to get;
Multiply out to obtain;
This is the same as;
This simplifies to
First thing to do, when you have to add 2 fractions, you have to make both denominators equal. 14/6 = 0.84, so can't multiply or divide any fraction by a whole number to get the other denominator.
So, you multiply each fraction by the denominator of the other fraction. Which means that you multiply 5/14 by the denominator of 1/6 which is 6, and you multiply 1/6 by the denominator of 5/14 which is 14.
5/14 + 1/6 = 30/84 + 14/84
Then you join both fractions to make them under one denominator, since both denominators are equal.
30/84 + 14/84 = (30+14)/84 = 44/84.
Now, you need to simplify the fraction: you divide both numerator and denominator by 4:
44/84 = 11/21
So 5/14 + 1/6 = 11/21
Hope this Helps! :)
45 = 3x3x5
Or you could simplify it to 3^2x5
Answer:
85,910
You get this because whenever there are three digits after a number you add a comma as seen in the number there are three digits after 85 so you add a comma.
Hope it helps bai!
