The quadratic equation x2 – 2x – 3 = 0 by completing the square is x = 1, −3
What is a quadratic equation?
Quadratum, the Latin word meaning square, is where the word “quadratic” originates. An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
[tex]x^{2}[/tex]+2x−3 = 0
Add 3 to both sides of the equation.
[tex]x^{2}[/tex]+2x=3
To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b.
(b/2)2=[tex](1)^{2}[/tex]
Add the term to each side of the equation.
[tex]x^{2}[/tex]+2x+[tex](1)^{2}[/tex]=3+[tex](1)^{2}[/tex]
Simplify the equation.
x2+2x+1=4
Factor the perfect trinomial square into [tex](x+1)^{2}[/tex]
[tex](x+1)^{2}[/tex]=4
Solve the equation for x.
x =1, −3
Hence, x =1, −3 is the correct answer.

What is the ground distance between A and B . Measure 16cm from the paper if the scale is 1:50,000
The distance between points A and B is 800000 cm which is equal to 8 km.
What is the meaning of a scale of 1:50,000?
A map would often indicate its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters).
Calculation of Distance between A and B = 16 x 50,000 = 8,00,000 cm.

Factors Affecting Population Distribution in Ethiopia
In Ethiopia, the population distribution is affected by the factors are the climatic conditions, altitude, and the soil of that region.
What is population distribution?Population distribution is referred to as the particular region of a country in which the maximum number of people are residing.
The population of Ethiopia is concentrated in the regions of highlands where there is adequate rain, the richness of soil for cultivation, and the temperature is moderate, that is, not too cool or not too high. According to a 1990 study, about 14 % of people lived in the cool climatic zones, approx. 11% were in the hot climatic zones and the rest of the people lived in moderate zones. There is lesser agriculture in the zones of cool climates due to less rain while more agriculture activity could be seen in moderate climates due to abundant rains.Therefore, the factors affecting the population of Ethiopia are described above.

Most often, we talk about two-dimensional shapes, such as the ones you draw on paper, like circles, triangles, and rectangles. The very first house I drew as a kid consisted of a square for the building of the house, a triangle for the roof, a rectangle for the door, and small squares for the windows. You might have drawn something similar. All we did was put together different geometric shapes to create a picture.

Challenger Deep is a feature of_____ Ocean.
Answer:
Pacific
Explanation:
Answer:
Challenger Deep is a feature of the Pacific Ocean.
How difficult is it to get to Challenger Deep?With a depth of 10,902 to 10,929 m by direct measurement from deep-diving submersibles, remotely controlled vehicles, and benthic landers and slightly more by sonar bathymetry, the Challenger Deep is the deepest known point in the Earth's seafloor hydrosphere. The H.M.S. Challenger, a Royal Navy vessel that traveled around the world in the 19th century to investigate the waters, gave rise to the name Challenger Deep. On March 23, 1875, the Challenger crew performed an action they would go on to repeat more than 500 times over the course of their three-and-a-half-year expedition: they dropped a hemp rope weighed down with iron sinkers into the water to gauge the depth of the ocean floor. This was done 140 miles southwest of Guam, at the far western edge of the Pacific Ocean. 4,475 fathoms are the result (8,184 m). The sounding wasn't a record, but it was the first one conducted near the Mariana Trench, which is now known to be the deepest place on Earth. Even if it is so deep that it could easily contain Mount Everest in its entirety, we won't be able to view the mountain's summit above the water. Although the phrase "Challenger Deep" is frequently used to refer to the deepest point on Earth, neither a sounding nor a specific area of the ocean bottom can be considered Challenger Deep. This is "deep." I will return to this shortly. Eight tons per square inch of crushing water pressure, or around 1,000 times the average air pressure at sea level, is present at the bottom of the trench. As depth deepens, pressure rises. It has been more than 50 years since the first and only time that humans entered the Challenger Deep. Imagine yourself taking on such intense pressure that, should your submersible vehicle malfunction, your body would be squeezed before you would drown. You won't find a single vertebra there as a result of this. For us as humans, it's a very other universe. There is also total darkness, which will scare the living daylights out of you. Therefore, it is true to say that we have learned considerably more about space than we have about our seas.
