Answer:

\boxed{\boxed{\dfrac{2}{x^2+x}-\dfrac{1}{x}=\dfrac{1-x}{x(x+1)}}}

Step-by-step explanation:

The given expression is,

\dfrac{2}{x^2+x}-\dfrac{1}{x}

Factoring x^2+x,

x^2+x=x(x+1)

Hence,

=\dfrac{2}{x(x+1)}-\dfrac{1}{x}

\mathrm{Least\:Common\:Multiplier\:of\:}x\left(x+1\right),x = x\left(x+1\right)

So,

=\dfrac{2-(x+1)}{x(x+1)}

=\dfrac{2-x-1}{x(x+1)}

=\dfrac{1-x}{x(x+1)}

K (3x - 2) = 4 - 6x<br> Find the value of k
svlad2 [7]

Hello!

In this case, you are looking for a value of K so the left side of the equation is equal to the right.

The left side of the equation is K (3x - 2), and the right is 4 - 6x. To get the left side to equal the right, you can set K = -2. This is because of the <u>distributive property</u>: a number just outside of the parenthesis can distribute to everything in the parenthesis like so:

-2 (3x - 2) = (-2 * 3x) - (-2 * -2) = -6x + 4

Therefore, your answer is K = -2.

Hope this helps!

(Side note: a better way to do this would be to divide both sides by 3x - 2)

Help please? It would help a lot :)

a. P(2 or 4) is the probability of rolling either a 2 or a 4 on the die.
P(2 or 4) is equal to P(rolling a 2) + P(rolling a 4)
1/6 + 1/6 = 2/6 = 1/3

b. P(greater than 2) is equal to P(3) + P(4) + P(5) + P(6)
1/6 + 1/6 + 1/6 + 1/6 = 4/6 = 2/3

7. The probability of getting a head is 1/2. If you toss the coin two times, there are four different possibilities. HH, TT, HT, or TH. The answer would be 1/4, you get that by multiplying 1/2 by 1/2 again.
