Answer:
The answer is ± in exact form or , in decimal form.
Step-by-step explanation:
To solve this problem, start by moving all terms to the left side of the equation and simplify. Simplify the equation by subtracting 12 from both sides of the equation and squaring , which will look like . Next, simplify the equation again, which will look like .
Then, use the quadratic formula to find the solutions. The quadratic formula looks like.
For this problem, the quadratic variables are as follows:
The next step is to substitute the values , , and into the quadratic formula and solve. The quadratic formula will look like . To simplify the equation, start by simplifying the numerator, which will look like . Then, multiply 2 by 1 and simplify the equation, which will look like . The final answer is ± in exact form. In decimal form, the final answer is , .

Answer:
True
Step-by-step explanation:
- 4 ÷ 7 = 0.5714
- 18 ÷ 31.5 = 0.5714
- Because they are the same result, the two fractions are equal. Therefore, the equation is true.
I hope this helps!
Answer:
D is right option
Step-by-step explanation:
Similarities:
<em>Both the biomes experience less precipitation due to this they have a less diversity of flora and fauna as compared to other biomes like savanna, grasslands, chaparral etc. Let us see how they differ from each other!</em>
Low rain fall _ annual rainfal of lessthan 20cm in deserts, 15-20cm in tundra
Minimal life_ only small shurbs can survive in both kind of environments
Poor drainage.. In deserts, though sandy soil may seem much porous, these are most flood prone areas of world. The tundra is characterised by permafrost soils ie, under the thin layer of soil, a thick ice sheet is present and hence is no seepage.
High range of temperatures: In tundra, the maximum temperatures are recorded in summer (abt 10^C) and minimum during winter(-20 to -30^C). While, in desert too, the temperature range is high but diurnally ie, nights are too cold and day time is scorching.
