To find the common difference in the sequence 8, 16, 24, 32.... we must find what the difference between two consecutive terms is. A simple way to do this is to find the difference between the first term and the second term. That means that we have to do the second term - the first term. That means we do 16 - 8 which gives us that the common difference is 8.
Answer: C) (x + 5i)(x - 5i)
<u>Step-by-step explanation:</u>
x² + 25 can be rewritten as x² - (-25)
Now use the difference of squares to factor: a² - b² = (a + b)(a - b)
√x² = x √-25 = 5i
--> x² + 25 = (x + 5i)(x - 5i)
Answer:
45 students are in the Environmental Club
Step-by-step explanation:
25/100 = x/180 (cross multiply)
(180 * 25) / 100 = 45
Answer:
1st markdown = $324
2nd markdown = $259.20
Step-by-step explanation:

1st 6 months = 10% down
= 90% of 360
= <u>324</u>
2nd 6 month = 20% down of first 6 month
= 20% down of 324
= 80% of 324
= <u>259.20</u>
