What two numbers multiply to negative 18 and add to negative 3

1 answer:

6 0

-3 and 6

-3 x 6 = -18
-3 + (6) = 3

 x2 + 3x - 18 = 0


 (X - 3 ) (X + 6)

To summarize, since -3 and 6 multiply to -18 and add up 3, you know that the following is true:

 x2 + 3x - 18 = (X - 3 ) (X + 6)

Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. What is the latitude of

erica [24]

Answer:

${\theta}=12.53 degrees$ ≈13degrees

Step-by-step explanation:

It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,

Using the formula, $S=r{\theta}$ where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get

$1400=6400{\theta}$

⇒ ${\theta}=\frac{14}{64}$

Therefore, ${\theta}=\frac{14}{64}{\times}\frac{180^{{\circ}}}{{\pi}}$

⇒ ${\theta}=\frac{2520}{200.96}$

⇒ ${\theta}=12.53 degrees$

Thus, the latitude of B is=12.53 degrees≈13degrees

What is 3/5 estimated to nearest whole number

alukav5142 [94]

Three fifths is less than one, but since it is greater than 1/2 three fifths is nearest to one. NOT SIXTY!!! 3. 60 — = — 5. 100 60/100 is NOT bigger than one. Instead, it is close to one but a fraction. Since it is bigger than 50/100, it would be rounded to 1. Hope this helped
