Two consecutive even positive integers have a product of 2,400. What is the smaller of the two numbers?
Flura [38]

Answer: <u>Option C; 48</u>

Explanation:

Let one number = x

Other number = x+2

According to question-

[x] [x+2] = 2400

x^{2} + 2x - 2400 = 0

Solving this equation, we get-

[x - 48] [x - 50 ] = 0

x = 48 or 50

Since 48 is the smaller number here, answer is option C

Does human intervention affect small-scale ecosystems differently than large-scale ecosystems?
sdas [7]

Answer: No

According to <u><em>BBC</em></u>, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.

According to <u><em>National Geographic</em></u>, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
