Answer:
1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
Explanation:
2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
Answer:

Explanation:
Answer:
B. -3
Explanation:
Our equation is: 
. We see that both sides have a term with denominator ax - 2, so let's add 
to both sides:
Now multiply both sides by ax - 2:
We essentially want to make the terms on each side match. Look at the coefficient of x² on the left side: it's 24. That means on the right side, it should be 24, as well. Then, set -8a equal to 24:
-8a = 24
a = -3
Thus, the answer is B.
