This expression of is identical to the statement in factored form of
4 (x² - 2x) 2 (x² - 3) is 2 (x - 1) (x – 3)
What is meant by equivalent?When two or more fractions can be reduced to one another, they are said to be equivalent. As an illustration, the equivalent fractions of 1/5 are 5/25, 6/30, and 4/20, which when simplified yield the same fraction, i.e. 1/5. Equivalent expressions are those that, despite appearing differently, perform the same operations. When the same value of the variable is entered, the results of two algebraic expressions that are equal have the same value.When writing equivalent fractions, the numerator and denominator are both multiplied or divided by the same number. This explains why these fractions combine to equal one number.Given,
4(x² – 2x) – 2(x² – 3)
We would first of all expand the expression given
This becomes
= 4x² - 8x - 2x² + 6
Rearrange to enable us simplify
4x² - 2x² - 8x + 6
= 2x² - 8x + 6
Factorize
2 (x² - 4x + 3)
factorizing further using the factors of 3 that add up to -4
2(x² - x - 3x + 3)
pick out the common factors
2 (x (x - 1) - 3 (x - 1)
2 (x - 1) (x - 3)
Hence, the correct answer is A) 2(x - 1) (x – 3)

Uma mulher com prou 171 capacetes e 1/9 veio com defeitos quantos capacetes estavam perfeitos para uso
Responder:
152 capacetes
Explicação passo a passo:
Dado que:
Número de capacetes = 171
Fração com defeito = 1/9
Portanto, número de capacetes com defeito:
1/9 * 171 = 19 capacetes
Número de capacetes sem defeitos:
Número total de capacetes - número de capacetes defeituosos
171 - 19 = 152 capacetes

Tina bought a painting while on vacation in 2009. The table below shows the value of the painting in2009,2010,and2011. If this trend continues, what will be the value of the painting in 2030?
Year: 2009, 2010, 2011
Value of painting: $75, $88.50, $104.43
A) $1,915.42
B) $2,044.19
C) $2,103.73
D) $2.279.55
E) $2,424,28
(The Year and value thing is a table, the first one listed on year goes with the first one listed on the value and so on)
Please help!!
Answer:
The answer is E
Step-by-step explanation:
We first are going to look at our first term on the table(the number that comes up first) which is $75.
Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).
Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation.
We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!
Equation: F(x)= 75(1.18) ^21
The answer that you get is: $2424.28
Let me know if you have any questions!
:)
The value of the painting in 2030 would be $2424.28.
What is the value of the painting in 2030?From the given table, it can be observed that the painting increases in value over the years. Increase in value of the painting from 2009 to 2010 = ($88.50 / $75) - 1 = 18%.
The formula for determining the future value of the painting is:
FV = P (1 + r)^nm
FV = Future value
P = Present value
R = interest rate
N = number of years
The value of the painting in 2030 = $75 x (1.18)^21 = $2424.28

James earns 20 allowance every month and 30 for each a on his report card
PART A- Identify the independent and dependent variables
PART B- Write a function that describes the situation
f(x)
Answer:
Part A - the independant variable is the monthly allowance, and the dependent amount is the one that he has to get As for in order to receive it.
Part B - y = 30x + 20
Step-by-step explanation:
Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.
Part B; The function for this situation is;
⇒ f (x) = 30x + 20
Where, x is number of report card.
What is mean by Function?
A relation between a set of inputs having one output each is called a function.
Given that;
James earns 20 allowance every month.
And, Earn 30 for each a on his report card.
Now,
Let number of report card = x
Then, We can formulate the equation as;
⇒ f (x) = 30x + 20
Where, x is number of report card.
Hence, The independent variable is monthly allowance and the dependent variables is earns in report card.
Thus,
Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.
Part B; The function for this situation is;
⇒ f (x) = 30x + 20
Where, x is number of report card.

Answer:
x = 12
y = 60
Step-by-step explanation:
Remark
What you are given is a parallelogram. These figures have opposite sides equal and parallel. Parallelograms also have angles opposite each other equal. Put into simpler language
Equations
y = 60 Opposite angles are equal
x + 3 = 15 Opposite sides are equal.
Solution
y = 60 (see the remark)
x + 3 = 15 Subtract 3 from both sides
x = 15 - 3
x = 12

Answer:
the rate is 4.36%
Step-by-step explanation:
The computation of the pre tax cost of debt is shown below:
Given that
NPER = 24 × 2 = 48
FV = $1,000
PMT = $1,000 ×5% ÷ 2 = $25
FV = $1,175 - $80
= $1,095
The formula is shown below:
= RATE(NPER;PMT;-PV;FV;TYP
After applying the above formula, the rate is 4.36%
