9; because 18 subtract 9 equals 9. OR- Think of it as addition. 9+what=18? 9.

Rewrite 24 * x in a different way, using the commutative property of multiplication. Note that x represents a real number.

Ivan

The communicative property means that multiplied numbers can be multiplied in any order.

3*2*4 is the same as 2*4*3. The answer will be the same.

So (24 * x) is the same as (x * 24).

Hope this helps! :)

The length of a rectangle is 18 cm and the width is 6 cm. A similar rectangle has a width of 2 cm.What is the length of the seco

Zielflug [23.3K]

Given:

Two rectangles are similar.

Length of first rectangle = 18 cm

Width of first rectangle = 6 cm

Width of second rectangle = 2 cm

To find:

The length of the second rectangle.

Solution:

We know that the corresponding sides of similar triangles are proportional. So,

$\dfrac{\text{Length of first rectangle}}{\text{Width of first rectangle}}=\dfrac{\text{Length of second rectangle}}{\text{Width of second rectangle}}$

Let x be the length of the second rectangle. Then,

$\dfrac{18}{6}=\dfrac{x}{2}$

$3=\dfrac{x}{2}$

$3\times 2=x$

$6=x$

Therefore, the length of the second rectangle is 6 cm.

Answer:

19.41 units

Step-by-step explanation:

<u>Given coordinates of points;</u>

(-10, 9)
(-6, -10)

To determine the distance between the two points, the distance formula is required. The distance formula is used where it is not possible to calculate the distance through a straight line. The distance formula is expressed as,

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

The distance between the two points can be determined by plugging the coordinates into the formula;

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$
⇒ $\sqrt{[-6 - (-10)]^{2} + [-10 - 9]^{2} }$

Then, we can simplify the root as needed to determine the distance;

⇒ $\sqrt{[-6 + 10]^{2} + [-19]^{2} }$
⇒ $\sqrt{[4]^{2} +361 }$
⇒ $\sqrt{16 +361 }$
⇒ $\sqrt{377}$

Finally, we need to convert the root into decimals (stated in question). It is impossible to determine the root in decimal form. Therefore, I used a calculator to determine the distance in decimal form.

⇒ $\sqrt{377}$ ≈ 19.41 units [Using calculator]

Therefore, the distance between the two points is about 19.41 units.
