12 because if u multiply 3*4 it is 12 and 4*3 is 12 so they both have 12 in common.

To find common denominators
you may take each denominator and provide the acceptable factors.

factors of 3: 1 , 3 , 6 , 9 , 12....ETC
factors of 4: 1 , 2 , 4 , 8 , 12...ETC

Note that they both have a common number of 12

So you will multiply the 1st fraction by 4 and the 2nd by 3

4(1/3) = 4/12
3(1/4) = 3/12

no need for the last part unless if you are proceeding with different properties.

Find the height of a right circular cone if the slant height is 4 units and the radius is 2 units

k0ka [10]

The slant height of the right circular cone will be $l=2\sqrt5}$

<h3>What is slant height of cone? </h3>

The formula for the slant height of the cone is given as:

$l^2=r^2+h^2$

Here we have

r=2 units

h=4 units

By putting the values we will get

$l=\sqrt{4^2+2^2$

$l=\sqrt{16+4$

$l=\sqrt{20}$

$l=2\sqrt{5}$

Hence the slant height of the right circular cone will be $l=2\sqrt5}$

Solve the following equation. Remember to check for extraneous solutions 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).

xxMikexx [17]

Answer:

-1, 2, 6

Step-by-step explanation:

We have to solve the equation as follows: 1/(x-6) + (x/(x-2)) = (4/(x²-8x+12)).

Now, we have, $\frac{1}{x-6} +\frac{x}{x-2} = \frac{4}{x^{2}-8x+12 }$

⇒ $\frac{(x-2)+x(x-6)}{(x-2)(x-6)} = \frac{4}{x^{2}-8x+12 }$

⇒ $\frac{x-2+x^{2}-6x }{(x-2)(x-6)} =\frac{4}{(x-2)(x-6)}$

⇒ $\frac{(x-2)(x-6)}{x^{2}-5x-2 }=\frac{(x-2)(x-6)}{4}$

⇒ $(x-2)(x-6)[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$

⇒ $(x-2)(x-6) =0$ or, $[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$

If, (x-2)(x-6) =0, then x=2 or x=6

If, $[\frac{1}{x^{2} -5x-2} -\frac{1}{4} ]=0$ , then $x^{2} -5x-2=4$

and (x-6)(x+1) =0

Therefore, x=6 or -1

So the solutions for x are -1, 2 6. (Answer)
