The answer is 3.33%. Anna reduced her CO2 emissions by 3.33% from using 600 gallons of gas annually than from using 900 gallons of gasoline annually. I arrived to this answer through multiplying gallons by 20 pounds of C02 (600*20) = 12000; (900*20) = 18000. Then I proceeded to subtract 12000 from 18000 which yielded me 600 (18000-12000 = 600). Lastly, I divided 600 by 18000 and it gave an answer of .0333. Then, I converted it to percent, thus, yielding me the answer of 3.33%.
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5

Answer:
x(x+y+3)(x+y-3)
Step-by-step explanation:
x³+2x²y+xy²-9x
= x((x²+2xy+y²)-3²)
= x((x+y)² - 3²)
= x(x+y+3)(x+y-3)
