Answer:

4(x - 3)

Step-by-step explanation:

When you put brackets around a binomial (has 2 parts separated by a plus / - sign), you must take out a common factor from both terms separated by the + or - sign

A only has the 4 taken away from the x. The answer is not A

B has the 3 removed from the 12, not the x, so B is not the answer.

C that's the answer.

I am an improper fraction whose numerator and denominator are made of odd digits only. In my simplest form, my representation as

ASHA 777 [7]

Answer:

The fraction is = $\frac{21}{9}$

Step-by-step explanation:

In simplest form the fraction is represented in mixed number as $2\frac{1}{3}$ .

The fraction form of the mixed number can be given as :

$2\frac{1}{3}=\frac{7}{3}$

Let the fraction be = $\frac{7x}{3x}$ [As multiplying same numbers to numerator and denominator does not affect the proportion.

Sum of numerator and denominator is = 30

This, can be represented as:

$7x+3x=30$

Solving for $x$ .

$10x=30$

Dividing both sides by 10.

$\frac{10x}{10}=\frac{30}{10}$

$x=3$

So, the fraction will be = $\frac{7\times 3}{3\times 3}$

⇒ $\frac{21}{9}$

Which expression is equivalent to square root 25x^9

tekilochka [14]

√((25x^9y^3)/(64x^6y^11)) doing the normal division within the radical

√((25x^3)/(64y^8) then looking at the squares within the radical...

√((5^2*x^2*x)/(8^2*y^8)) now we can move out the perfect squares...

(5x/(8y^4))√x

So it is the bottom answer...
