What is the least common denominator of 4/x * -4/2x^2?

The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it 

Hope this helps :)

Answer: 2x^2

Justification:

First we must make the expressions clear.

It seems you are asking about the least common denominator of 4/x and - 4/ (2x^2).

I will not simpligy the second denominator and will find the least common denominator of x and 2x^2.

The least common factor is the simplest (smallest) factor that contain all the factors given.

So, the least common denominator of both x and 2x^2 is the simplest monomial that contains them.

To find that least common factor you take the  product of:

- least common multiple of the coefficients: in this case the coefficients are 1 and 2, so the least common coefficient is 2.

- the product of the different letter raised to the highest power: in this case the only letter is x and the highest power is 2, so it is x^2

Therefore the lease common denominator is the product of 2 and x^2 which is 2x^2.

Answer:

The value of x = 10.

Step-by-step explanation:

From the given triangle,

  • The value of angle M = (3x + 28)°
  • The value of angle K = (5x - 18)°
  • The value of angle L = 90°

We know that the sum of a triangle is 180°.

i.e.

K + L + M = 180°

(5x - 18)° + 90° + (3x + 28)° = 180°

5x-18+90+3x+28=180

5x+3x-18+90+28=180

8x-18+90+28=180

8x+100=180

8x=80

\frac{8x}{8}=\frac{80}{8}

x=10

Therefore, the value of x = 10

3(3−3)=2(+3)−30 how do I do this???? I'm in 10th grade and this confuses me every time.
astra-53 [7]
Well when you simplify it you get this,

0=-24,


Do what’s inside the parentheses first

3-3 is 0, 3•0 is 0

2•positive 3 is 6

6- -30 is -24

So you have 0=-24

Or just -24 :)
