12x²+4xy-100=0. The equation that represents the statement of the problem is 12x²+4xy-100=0.

The equation is represents by "Four times an unknown integer, multiplied by three times the unknown integer plus a different unknown integer, equals 100."

First, we have the statement "four times an unknown integer", this is:

Then, multiplied by three times the unknown integer plus a different unknown integer, that is:

4x(3x+y)

And finally, the equation above is equals to 100.

4x(3x+y)=100

Operating

(4x)(3x)+(4x)(y)=100

12x²+4xy=100

Then, subtracting 100 on both sides of the equation.

12x²+4xy-100=100-100

Obtaining

12x²+4xy-100=0

Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0

What is a common factor for the two fractional terms StartFraction 5 over 8 EndFraction x andStartFraction 11 over 8 EndFraction

Dafna1 [17]

Answer:

$\frac{1}{8x}$

Step-by-step explanation:

Given two fractional terms $\frac{5}{8x}\ and\ \frac{11}{8xy}$ . Their common factor is a value or function that can go in both fractional terms. The terms can be written as shown.

$\frac{5}{8x} = 5 *\frac{1}{8x}$

$\frac{11}{8xy} = 11 * \frac{1}{8x} * \frac{1}{y}$

It can be seen from the both equations that they both have $\frac{1}{8x}$ as one of their factors i.e <em>1/8x is common to both fractional terms</em>. This gives the common factor for the two fractional terms as $\frac{1}{8x}$

This is the simplest form $4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2})$ .

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

$\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2} )$ is an expression.

<h3>How to make it simple?</h3>

$\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2} )$

On simplifying, we have

$\rm 4\sqrt{2} (x)^{\frac{3}{2}} * ( 3\sqrt{10} x^2 - \sqrt{5} x^{\frac{3}{2}})\\\\24\sqrt{5} x^{\frac{7}{2}} - 4\sqrt{10}x^3\\\\4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2} )\\$
