Answer: -6 - 5k
Step-by-step explanation:
-3(2+4k) +7(2k-1)
-6+(-12k) + 14k -7k
-6 -12k + 14k - 7k
-6 -5k

Answer: carbon cycle showes us the central importance of carbon in the biosphere.Carbon moves from one storage reservoir to another through a variety of mechanisms .biosphere is important because understanding how moves helps us to understand biological processes and factors that influence them.
Step-by-step explanation: Carbon cycles through ecosystems. cells use oxygen to break down sugar and obtain energy which is a process called respiration. Carbon is released and cycled back into the atmosphere as carbon dioxide.When living things die and decay the rest of the carbon that makes up living matter is released. Carbon will move from fossil fuels to the atmosphere when fuels are burned.
Photosynthesis, Decomposition, Respiration and Combustion
F(x) = 5x³ + 24x² - 75x + 14
Set each given factor equal to 0 and obtain 4 values of x:
A) x = -1/2
B) x = 1/2
C) x = -2
D) x = 2
Now, use the hit and trial method to find the answer. We are looking for a value of x which will put f(x) = 0
5(-1/2)³ + 24(-1/2)² - 75(-1/2) + 14
=/= 0
5(1/2)³ + 24(1/2)² - 75(1/2) + 14
=/= 0
5(-2)³ + 24(-2)² - 75(-2) + 14
= /= 0
5(2)³ + 24(2)² - 75(2) + 14
= 0
Thus, the answer is D
