Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
Answer:
x = 12
Step-by-step explanation:
x - 5 = 84/x
x² - 5x = 84
x² - 5x - 84 = 0
x = (5 ±√(5² - 4(1)(-84))) / 2
x = (5 ± 19) / 2
x = -7 ignore
x = 12
Answer:
451 cm^3
Step-by-step explanation:
V = Bh (base area and height multiplied)
41 cm^2 x 11 cm = 451 cm^3
The y coordinates stay the same, so the answer is C. y = -3
The answer to this would be x = 20
