Answer:

The final solution is x = i√5, − i√5

Step-by-step explanation:

(x−1)(x2+5)=0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x−1=0

x^2+5=0

Set the first factor equal to 0 and solve.

x = 1

Set the next factor equal to 0 and solve.

The final solution is all the values that make (x−1)(x2+5)=0 true.

So, final solution is x = i√5, − i√5

Answer:

- 7

Step-by-step explanation:

6(- x - 3) = 24

-6x - 18 = 24

-6x = 24 + 18

-6x = 42

x = 42 ÷ - 6

x = - 7

Step-by-step explanation:

Given:

A city's population has increased 40% in the last 5 years and is now 53,782 people.

To find:

The population 5 years ago.

Solution:

Let x be the population 5 years ago.

A city's population has increased 40% in the last 5 years.

So, present population is

[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]

It is given that the present population is 53782.

[tex]1.4x=53782[/tex]

[tex]x=\dfrac{53782}{1.4}[/tex]

[tex]x=38415.7142857[/tex]

[tex]x\approx 38416[/tex]

Therefore, the population 5 years ago was about 38416.

Answer:

x = 4

Step-by-step explanation:

since it is an equilateral triangle, each angle is 60°. To find x, set up the equation 17x-8=60

17x = 68

x=4

Answer:

8x^2-5x

Answer:

Noise level increase by 1.5 per unit increase in number of persons

Step-by-step explanation:

The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.

The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.

Answer:

The first number line because a negative number plus a positive number would give you zero if the digit before the signs are the same (eg. -5+5=0)

Answer:

34 cm squared

Step-by-step explanation:

Complete it to full rectangle and calculate the area by multiplying width and length then calculate the area of red area and subtract it from the full rectangle's area

9×6 - 5×4 = 34 cm^2

The shapes that would be formed by the nets are:

a. Cuboid

b. square pyramid

A cuboid is a shape that is formed by the net that has six (6) flat faces with angles that are right angles.

The net in figure a above would form a cuboid shape when joined together.

A square pyramid is a thee-dimensional geometric shape that is formed by the net consists of a square base and four triangular sides which joined together at a common vertex.

The image attached below shows the shape that would be formed by the net in figure B, which would be a square pyramid.

Therefore:

a. Cuboid

b. square pyramid

Answer:

formula is speed equals distance/ time.

now, speed above is 85km/h and distance is 42km.

time therefore is 42/85 which is 0.494h

now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)

now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)
