Answer:

(x + 2)(x + 4)

Step-by-step explanation:

Factor out the given expression to obtain an equivalent expression. In this case, find factors of x² and 8 that, when combined using FOIL, will result in 6x.

Use the FOIL method. FOIL, stands for First, Outside, Inside, Last:

First:

x * x = x²

Outside:

x * 4 = 4x

Inside:

2 * x = 2x

Last:

2 * 4 = 8

Combine like terms:

x² + 4x + 2x + 8

x² + (4x + 2x) + 8

x² + 6x + 8

nikitadnepr [17]
16 - 4x > 9 - 5x   Add 5x to both sides
 16 + x > 9           Subtract 16 from both sides
        x > -7

Noah has drawn two triangle △MNO and △M'N'O' on the coordinate plane as shown below. (the image I pasted)
Ber [7]

Answer:

  choice C is correct

Step-by-step explanation:

The clockwise sequence of vertices MNO is the opposite of the counterclockwise sequence of vertices M'N'O', so it seems some sort of reflection is involved.

Length NO is 3 times length N'O', but length NM is only 7/3 times length N'M', so the figures are <em>not similar</em>. (The ratios of side lengths must be the same for the figures to be similar.)

___

Choice D includes only rigid transformations that would ensure congruence. Similar figures may also differ by a dilation factor, so C is the better choice.

The probability of both sample information and a particular state of nature occurring simultaneously is known as _____ probabili
Tcecarenko [31]

The correct answer is d.joint probability.

<h3>What is joint probability?</h3>

Given two random variables that are defined on the same probability space,the joint probability is a statical measure that calculates the likelihood of two events occuring together and at that same point of time.

In the given question it is said that the probability of both sample information and a particular state of nature occurring simultaneously.

So, when the state of nature of sample remains unchanged it will not affect the sample so does the output.

Hence when without affecting the nature of sample the sample information remains intact. If the nature of sample is changed the required out will also change.

⇒Since both the measure are occuring simultaneously without changing the nature of sample.

hence, it is joint probability.

whereas,

  • In conditional probability, the possibility of the event depends on the previous events,
  • In marginal probability the outcome is independent of another variable, and
  • in unconditional probability the chances that a particular even will occur without any external circumstances.

Hence, in the given condition the correct answer is d. joint.
