<h2>Hello There today we will solve your problem</h2>

Solve for x please :-

3(9+x)-31=20

_____________________

<h2>Definitions</h2>

To use the distributive property, we need to understand the formula to use it. This formula will ensure that you can easily solve any equation.

The distributive property is A(B + C) = AB + AC, where AB is the product of the values A and B and AC is the product of the values A and C.

First, let's notice that we are distributing a 2 into the parentheses, so we will mark this as our A value.

Then, our two values inside the parentheses are B and C respectfully.

3(9)+3(x)-31=20\\27+3x-31=20\\3x-31=-7\\3x=24\\x=8

What is the probability that the first card is a kingking and the second card is a kingking if the sampling is done with​ replac
IRINA_888 [86]
You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is 
4/52 on the first draw.

For the second draw the probability is the same.
4/52

The probability for both happening is 
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597

Lesechka [4]

Answer:

Solution : -\frac{3}{4}-\frac{3}{4}i

Step-by-step explanation:

-3\left[\cos \left(\frac{-\pi }{4}\right)+i\sin \left(\frac{-\pi \:}{4}\right)\right]\:\div \:2\sqrt{2}\left[\cos \left(\frac{-\pi \:\:}{2}\right)+i\sin \left(\frac{-\pi \:\:\:}{2}\right)\right]

Let's apply trivial identities here. We know that cos(-π / 4) = √2 / 2, sin(-π / 4) = - √2 / 2, cos(-π / 2) = 0, sin(-π / 2) = - 1. Let's substitute those values,

\frac{-3\left(\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}i\right)}{2\sqrt{2}\left(0-1\right)i}

=-3\left(\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}i\right) ÷ 2\sqrt{2}\left(0-1\right)i

= 3\left(-\frac{\sqrt{2}i}{2}+\frac{\sqrt{2}}{2}\right) ÷ -2\sqrt{2}i

= \frac{3\left(1-i\right)}{\sqrt{2}}÷ 2\sqrt{2}i = -3-3i ÷ 4 = -\frac{3}{4}-\frac{3}{4}i

As you can see your solution is the last option.
