After simplify of this equation 2x (3x + 4) - (3x ² + 8x - 2). We get, the two factors which are +√(-2/3), -√(-2/3).
Given Equation:
2x (3x + 4) - (3x ² + 8x - 2)
2x (3x + 4) - 3x ² - 8x + 2
6x² + 8x - 3x ² - 8x + 2
3x ² + 2
To find the factors
3x ² + 2 = 0
x ² = -2/3
x = ±√(-2/3).
Therefore, the factors of given equation are +√(-2/3), -√(-2/3).

Look at this incomplete multiplication problem.
154 times 63 = 462. 462 + question mark = blank
The missing value is
A. 904
B.9040
C.9240
Answer:
The answer is C
Step-by-step explanation:
The first step is to multiply 154 and 63 to find the product. The product of those two numbers is 9702.
So the the equation looks like...
462+ Blank = 9702
The easiest thing to do here is subtract 462 from both sides. So 9702-462 which would equal 9240.
So we'll say that the blank is x so now the equation says...
x = 9240

A rental car agency charges $180 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $382.50?
Answer:
810
Step-by-step explanation:
382.50-180= 202.5
202.5 / 0.25= 810
Hope this helps!
Answer:
810 miles
Step-by-step explanation:
$180 a week is the fixed cost so we subtract this first.
($382.50 - $180 = $202.50)
The number left is the amount of dollars charged per mile.
So if we divide this number by $0.25, we get how many miles travelled.
($202.50 ÷ $0.25 = 810 miles)
1 ÷ 200= 0.005

True

The unit method is a method of finding the value of one unit and then finding the value of the required number of units. For simplicity, always write what you calculate on the right and what you know on the left.The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.It is given that a truck driver drove 119 miles in 3 1/4 hours .
On simplifying the time , we get
[tex]3\frac{1}{4} =\frac{3\times4+1}{4}\\\\ 3\frac{1}{4} =\frac{13}{4}[/tex]
which means that truck driver drove 119 miles in [tex]\frac{13}{4}[/tex] hours .
Using unitary method , we get
[tex]\frac{13}{4}[/tex] hours is taken by driver to complete = 119 miles

let a be the event that the sum of the faces showing is 6 and let b be the event that the face showing on one die is twice the face showing on the other die.
PABc = 3/36
PABc = 1/12.
Two dice are tossed.
Assume that each possible outcome has 1/36.
Let A be the event the probability of getting some of the faces showing is 6.
A = 1,5,5,12,44,23,3
Let B be the event that the face showing one die is twice on the other.
That is,
B =1,22,12,44,23,66,3
There are 36-6=30 events in Bc
However, A and Bc will only be having 3 pairs together = 1,55,13,3
Therefore,
PABc = 3/36
PABc = 1/12.
How many outcomes are possible for the sum of the faces showing?
There are countless outcomes that could occur. The sum of the faces shown has an endless number of outcomes. This is due to the fact that there are an endless number of ways to flip a coin, which will produce various combinations on the faces that are displayed. The sum of the faces and the tails has an endless number of outcomes. There are only two outcomes that can occur while tossing a coin because the total number of outcomes is always even.

14. Wisco's winter carnival is coming up, and Mr. Raymond is in charge of ordering the craft kits again. He knows he ordered 13 boxes of snow globe kits last year but can't remember how many kits came in a box. He checks the records and finds that the school used 172 of the snow globe kits last year and had 10 left over after the event. How many snow globe kits come in each box?
Answer:
169
Step-by-step explanation:
Answer:
Assume x to be the number of snow globe kits that come in each box.
Then the equation that describes the given situation is
13x - 10 = 172
13x = 182
x = 14
So, the number of snow globe kits that come in each box is 14.
the age distribution of a population (relative proportions of people of different ages) is not important when considering the growth rate of that population.
It is False to state that the age distribution of a population is not important when considering the growth rate of that population.
What is the growth rate of a population?Population growth is the rise in the number of inhabitants in a population or scattered group and it is usually stated in percentage.
Researchers often focus on four primary elements when forecasting changes in population size:
Birth rates,Death rates (life expectancy),The beginning age profile of the population (i.e. elderly or relatively young individuals), and Migration.Other factors include:
Economic development Social and cultural factorsEducation, etcAge distribution and statistics allow the pace of population growth to rise or decline as it is linked to the level of economic development of a population. a fast-expanding country's population has a pyramid-shaped age structure, with a higher share of younger people of reproductive age.
Therefore, we can conclude that it is False to state that the age distribution of a population is not important when considering the growth rate of that population.
