(-4n^(2))* (5n^(7)):-20n to the power of 9
(2x)^(3)*(5x^(4 ))^(2): 200x to the power of 11
7 plus 9. 10 plus 6 gives you 16, as does 7 plus 9.
Answer:
x = 24
Step-by-step explanation:
y₂ - y₁
42 - 21 = 21
x + 21
3 + 21 = 24
So when y increases by 21, so does x.
x = 24
Answer:
Current impact in pollution units per day=21.6 billion pollution units per day
Step-by-step explanation:
1 person consumes 3000 kilo-calories per person
Current population=7.2 billion people
Total calories the entire population produces=(7.2 billion×3000)
1000 kilo-calories causes= 1 pollution unit
To get the impact of the entire population=(7.2 billion×3000)/1000=21.6 billion pollution units per day
