Answer:

1.922 miles is equivalent to 3.1 kilometers.

Step-by-step explanation:

Given:

1 km = 0.62 miles.

3.1 km = ? miles

Now, in order to find the number of miles equivalent to 3.1 km, we use unitary method with the help of the conversion factor.

From the conversion factor, we can conclude that kilometer is a smaller unit compared to that of mile.

So, conversion factor = $\frac{0.62\ miles}{1\ km}$

The formula to transform 'n' kilometers to miles is given as:

$=Conversion\ factor\times n$

Therefore, 3.1 km = $\frac{0.62\ miles}{1\ km}\times 3.1\ km$

3.1 km = $1.922$ miles

Therefore, 1.922 miles is equivalent to 3.1 kilometers.

Answer:

$x=4+2\sqrt{3}$

$x=4-2\sqrt{3}$

Step-by-step explanation:

<u>Completing the square</u>

when $ax^2+bx+c=0$

Given equation:

$3x^2-24x+40=28$

Subtract 40 from both sides:

$\implies 3x^2-24x=-12$

Divide both sides by 3:

$\implies x^2-8x=-4$

Add the square of half the coefficient of $x$ to both sides:

$(\frac{b}{2})^2=(\frac{-8}{2})^2=16$

$\implies x^2-8x+16=-4+16$

Factor the left side and simplify the right side:

$\implies (x-4)^2=12$

Square root both sides:

$\implies x-4=\pm\sqrt{12}$

Add 4 to both sides and simplify the radical:

$\implies x=4\pm\sqrt{4 \cdot 3}$

$\implies x=4\pm\sqrt{4}\sqrt{3}$

$\implies x=4\pm2\sqrt{3}$

Daniella wants to build a plot of land that has an area of 121 km 2.What is the length and width of the plot of the land?Explain

Orlov [11]

To find the area of a shape, in this case a square, you have to multiply the length and width. to find one of the sides, since this is a square, you can just find the square root of 121, which is 11. Ans. L: 11 W:11

hope this helps :)
