Question 21 pts

Pachacha [2.7K]

Answer:

x = -2 or x = -6 or x = sqrt(5) or x = -sqrt(5)

Step-by-step explanation:

Solve for x:

x^4 + 8 x^3 + 7 x^2 - 40 x - 60 = 0

The left hand side factors into a product with three terms:

(x + 2) (x + 6) (x^2 - 5) = 0

Split into three equations:

x + 2 = 0 or x + 6 = 0 or x^2 - 5 = 0

Subtract 2 from both sides:

x = -2 or x + 6 = 0 or x^2 - 5 = 0

Subtract 6 from both sides:

x = -2 or x = -6 or x^2 - 5 = 0

Add 5 to both sides:

x = -2 or x = -6 or x^2 = 5

Take the square root of both sides:

Answer: x = -2 or x = -6 or x = sqrt(5) or x = -sqrt(5)

What is the actual length of the living space if the length of the scale drawing is 16. 8 centimeters? Enter your answer in the

yaroslaw [1]

To solve the problem we must know about the Ratio.

<h2>What is Ratio?</h2>

A ratio shows us the number of times a number contains another number.

The length of the living space, in reality, is 21 meters.

Given to us

The scale is given as 2 centimeters equals 2.5 meters.

To find

the actual length of the living space if the length of the scale drawing is 16. 8 centimeters

<h3>Scale ratio</h3>

As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as

$\dfrac{\text{Length of the scale drawing}}{\text{Length in reality}} = \dfrac{2\ cm}{2.5\ meters}$

<h3>Length of the living space</h3>

Using the same scale ratio,

$\dfrac{\text{Length of the living space in scale drawing}}{\text{Length of the living space in reality}} = \dfrac{2\ cm}{2.5\ meters}$

$\dfrac{16.8}{x} = \dfrac{2\ cm}{2.5\ meters}\\\\x=\dfrac{16.8 \times 2.5}{2} = 21\ meters$

Hence, the length of the living space, in reality, is 21 meters.
