Answer:

12x^4-20x^2+32x=4x(3x^3-5x+8)

Step-by-step explanation:

<u>Common Factors</u>

An algebraic expression that is formed by sums or subtractions of terms can be factored provided there are numeric or variable common factors in all the terms.

The following expression

Z=12x^4-20x^2+32x

Can be factored in the constants and in the variable x.

1. To find the common factor of the variable, we must locate if the variable is present in all terms. If so, we take the common factor as the variable with an exponent which is the lowest of all the exponents found throughout the different terms. In this case, the lowest exponent is x (exponent 1).

2. To find the common factors of the constants, we take all the coefficients:

12 - 20 - 32

and find the greatest common divisor of them, i.e. the greatest number all the given numbers can be divided by. This number is 4, since 12/4=3, 20/4=5 and 32/4=8

3. The factored expression is

Z=12x^4-20x^2+32x=4x(3x^3-5x+8)

\boxed{12x^4-20x^2+32x=4x(3x^3-5x+8)}

Find the value of the variables in the simplest form
STatiana [176]

Answer:

x = 3

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3}

tan60° = \frac{opposite}{adjacent} = \frac{x}{\sqrt{3} } = \sqrt{3} ( multiply both sides by \sqrt{3} )

x = 3

A worker earns $5.15/h receives a raise. She now earns $6/h. Find the percent of increase in her hourly rate of pay.
Svetllana [295]

Answer:

The percentage increase in worker wages in hourly rate of pay is 16.5%

Step-by-step explanation:

Given as :

The Initial wages earn by worker = $ 5.15 per hour

The Final wages earn by worker = $ 6 per hour

Let The percentage increase in her hourly rate of pay = x %

Now, According to question

x % = \dfrac{\textrm Final earning - \textrm Initail earning}{\textrm Initial earning}

or, x =  \dfrac{\textrm $ 6 - \textrm $ 5.15}{\textrm $ 5.15} × 100

or, x = \frac{0.85}{5.15} × 100

or, x = 0.165 × 100

∴   x = 16.5%

So , Percentage increase in wages = x = 16.5 %

Hence The percentage increase in worker wages in hourly rate of pay is 16.5% Answer

Lance and 7 other friends go to an activity center together. They each pay $5.95 for dinner, $4 for laser tag, $3.60 for bowling
yulyashka [42]
The original equation: 8(5.95)+8(4)+8(3.60)+8(2.25)= $126.4

To answer the question you should add all of the numbers within the parenthesis together: 5.95+4+3.60+2.25= $15.8

Then multiply that answer times the total number of people: 8(15.8)= $126.4

No it is wrong
the product of it is
4x²+5x-6
so you have to multiply by 2
the naswer is 2(4x-3)(x+2)
