Answer:

the value of x is 2.

Step-by-step explanation:

5(3x - 4) = 2(2x + 1)

15x - 20 = 4x + 2

15x - 4x = 2 + 20

11x = 22

x = 22/11

x = 2

Create a factorable polynomial with a GCF of 3x. Rewrite that polynomial in two other equivalent forms. Explain how each form wa

sp2606 [1]

Answer:

The greatest common factor or GCF is the greatest common factor of 2 or more numbers or polynomials.

Step-by-step explanation:

We have to create a factor-able polynomial with a GCF of 3x.

We can take an example of : (x) = $3x^{3}+12x^{2}+3x$

We can rewrite this as : $3x(x^{2} +4x+1)$

WE can also rewrite it as : $12x^{2} +3x^{3}+3x$

Fiona purchased 400 m2 of plastic sheeting and needs to cut it into rectangles of area 500 cm2. This can be done with no waste.

hoa [83]

Answer:

8000

Step-by-step explanation:

The number will be ...

(400 m^2)/(500 cm^2) = 0.8 (m/cm)^2 = 0.8 ((100 cm)/(1 cm))^2

= 0.8·100^2 = 8000

Fiona can cut 8000 rectangles from the plastic sheeting she bought.

Solve the rational equation x divided by 6 equals x squared divided by quantity x minus 1 end quantity, and check for extraneous

pychu [463]

Answer:

$x = 0$ and $x = \textrm{negative one fifth}$

Step-by-step explanation:

Given:

The rational equation to solve is given as:

$\frac{x}{6}=\frac{x^2}{x-1}
$

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

$x\times (x-1)=6\times x^2\\x^2-x=6x^2\\\textrm{Bringing all variables to the right side, we get:}\\6x^2-x^2+x=0\\5x^2+x=0\\x(5x+1)=0\\x=0\ or\ 5x+1=0\\x=0\ or\ x=-\frac{1}{5}
$

Now, for $x=0$ , the rational equation is equal to 0. So, $x=0$ is a solution.

Also, $x=-\frac{1}{5}$ is also a solution as the equation's denominator is defined at that point.

So, no extraneous solution.
