What is the value of x in the diagram below?

VARVARA [1.3K]

Answer:

option B is the right option.

Step-by-step explanation:

<h3>Using leg rule</h3>

$\frac{bc}{ab} = \frac{ab}{bd}$

Plug the values:

$\frac{20}{12} = \frac{12}{x}$

Apply cross product property

$20 \times x = 12 \times 12$

Calculate the product

$20x = 144$

divide both sides of the equation by 20

$\frac{20x}{20} = \frac{144}{20}$

Calculate:

$x = 7.2$

hope this helps..

Good luck...

Answer:

3 $a^{4}$ - 48

Step-by-step explanation:

Given

(a + 2)(3a² + 12)(a - 2)

= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL

=(a² - 4)(3a² + 12) ← expand using FOIL

= 3 $a^{4}$ + 12a² - 12a² - 48 ← collect like terms

= 3 $a^{4}$ - 48

HELP...The volume of a rectangular prism is 36x^6y^8. The length of the prism is 4x^3y^5, and the width of the prism is 3xy^2. W

Margaret [11]

Answer:

$H = 3x^2y$

Step-by-step explanation:

Given

$V = 36x&^6y^8$

$L = 4x^3y^5$

$W = 3xy^2$

Required

Find the height of the prism

Volume (V) is calculated as:

$V =LWH$

Substitute values for V, L and W

$36x^6y^8 =4x^3y^5 * 3xy^2 * H$

Make H the subject

$H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}$

$H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}$

$H = \frac{36x^6y^8}{12x^4*y^7}$

Divide:

$H = 3x^{6-4}y^{8-7}$

$H = 3x^2y$

The height of the prism is: $3x^2y$

to raise money for her school field trip, Jane is selling candles. She has a large cancel for $8, and a small candle for $5. If

Fed [463]

Answer:

45 large candles
53 small candles

Step-by-step explanation:

Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...

8c +5(98-c) = 625

3c + 490 = 625 . . . . . . eliminate parentheses, collect terms

3c = 135 . . . . . . . . . . . . subtract 490

c = 45 . . . . . . . . . . . . . . divide by 3

Jane sold 45 large candles and 98-45 = 53 small candles.
