1/3!

six numbers on a die, only 5 and 6 are greater than 4 so that’s two numbers out of the six total that are greater than 4. 2/6 simplifies to 1/3!

For this question we have to take LCM of the fractions to simplify it and process further. So, by LaTeX interpreter equation editor, Here we go.

$\mathbf{Least \: Common \: Multiplier: 3x}$

$\mathbf{\dfrac{2}{x} \times 3x + \dfrac{1}{3} \times 3x - \dfrac{4}{x} \times 3x}$

Combine the fractions to multiply the numerator.

$\mathbf{\dfrac{2 \times 3x}{x} + \dfrac{1 \times 3}{3}x = \dfrac{4 \times 3x}{x}}$

$\mathbf{\dfrac{6x}{x} + \dfrac{3}{3}x = \dfrac{12x}{x}}$

$\mathbf{6 + x = 12}$

Just subtract both of the current sides by the numbered value "6".

$\mathbf{6 + x - 6 = 12 - 6}$

$\boxed{\underline{\mathbf{Final \: \: Answer: \: x = 6}}}$

Hope it helps.

What is the equation of a quadratic function p with rational coefficients that has a zero of 3-i

Kryger [21]

Answer:

p = x² − 6x + 10

Step-by-step explanation:

Complex roots come in conjugate pairs. So if 3−i is a root, then 3+i is also a root.

p = (x − (3−i)) (x − (3+i))

p = x² − (3+i)x − (3−i)x + (3−i)(3+i)

p = x² − 3x − ix − 3x + ix + (9 − i²)

p = x² − 6x + 10

You can check your answer using the quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ 6 ± √(36 − 40) ] / 2

x = (6 ± 2i) / 2

x = 3 ± i
