24 +80 distributive property
2 answers:
Answer:
.
Step-by-step explanation:
We are asked to apply the distributive property to solve our given expression .
First of all, we will find greatest common factor of 16 and 36 as:
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
We can see that the greatest common factor of 24 and 80 is 8.
We can rewrite our given sum as:
Using distributive property , we will get:
Therefore, our expression would be .

Answer:
C
Step-by-step explanation:
So, we started out with 2,400 black rhinos.
And we know that they are declining at a rate of 10% per year.
In other words, each subsequent year will only have <em>90%</em> of the previous year's rhinos.
Therefore, our function is:
We can do some elimination first.
First, the starting point or y-intercept <em>must </em>be 2400 since that's the number of rhinos we started out with.
Therefore, we can eliminate A and D.
From the remaining choices B or C, we can technically also eliminate B. This is because from our function, we know it's exponential decay, and exponential decay is <em>not</em> a straight line.
However, to double check, let's check the population after 10 years using our function. So:
Use a calculator:
So, after 10 years, the population should be around 840.
B is definitely <em>not</em> 840 (at x=10). However, C is right around it.
Therefore, we can conclude that C is the right answer.
And we're done!
