Answer: A
Step-by-step explanation:
Answer:
Carbon has 6 protons while oxygen has 8 protons.
Step-by-step explanation:
Let x be the number of protons in carbon and y be the number of protons is oxygen.
ATQ: 2x+y=20 and x+2y=22. Solving it, we will get x=6 and y=8
The area of the clock is 153.86(preferred)/153.94 or 49n n=pi
14/2 is 7 7*7=49 49 x pi is 153.94
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:

Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is

Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots
, you can factor the expression as 
In this case, the solutions are
, which yields the factorization

Exercise 4:
When you multiply two powers of the same base, you add the exponents:

So, in your case, you have
