Answer:

x³ + 5x² + 2x - 8

Step-by-step explanation:

1) Distribute

(x + 4) (x² + x - 2)

x(x² + x - 2) + 4 ( x² + x - 2)

2) Distribute

x(x² + x - 2) + 4 (x² + x - 2)

x³ + x² - 2x + 4 (x² + x - 2)

3) Distribute

x³ + x² - 2x + 4 (x² + x - 2)

x³ + x² - 2x + 4x² + 4x - 8

4) Combine like terms

x³ + x² - 2x + 4x² + 4x - 8

x³ + 5x² - 2x + 4x - 8

5) Combine like terms

x³ + 5x² - 2x + 4x - 8

x³ + 5x² + 2x - 8

Step-by-step explanation:

There are 3 triangles in the picture: the one on the left, the one on the right, and the overall triangle. We must first find the areas of the two smaller triangles before finding the area of the whole thing.

To find the area of a triangle, you must multiply the two legs of the triangle by each other and then divide that number by 2. For the left triangle, this would be [tex](4*4)/2=8[/tex], meaning it has an area of 8 square meters. For the right triangle, this would be [tex](4*3)/2=6[/tex], meaning the triangle on the right has an area of 6 square meters.

There are multiple ways to find the area of the big triangle, since the hypotenuse of the left triangle has been rounded. One way to find the area of the big triangle,is to add the areas of the two smaller triangles: [tex]8+6=14[/tex] square meters. For a more exact answer, we would solve [tex](5.7*5)/2=14.25[/tex]sqaure meters using the legs of the big triangle.

Answer:

inequality form: x [tex]\leq[/tex] -2 or x > 3

interval notation form: (-∞,-2] ∪ (3,∞)

Step-by-step explanation:

I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.

Answer:

144 deaths

Step-by-step explanation:

So, assuming it's not a leap year 30,300 must be divided by the number of days in the year to get the daily amount.

30,300/365 = 114.339....

since 3 is not greater than 5, the 144 does not round up but stays the same.

(Since you cannot have a fraction of a death)

114 is your answer

The value of z test statistics is 2.83.

Simply said, a z-score, also known as a standard score, informs you of how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.

You can plot a z-score on a normal distribution curve. The range of Z-scores ranges from -3 standard deviations (which would be on the far left of the normal distribution curve) to +3 standard deviations (which would fall to the far right of the normal distribution curve). You must be aware of the mean and population standard deviation in order to use a z-score.

Given mean = x = 36.1 inches

standard deviation = σ = 0.3

sample size = n = 72

and μ = 36.1

here z = (x - μ)/(σ/[tex]n^{1/2}[/tex])

z = (36.1 - 36 )(0.3/[tex]72^{1/2}[/tex])

z = 0.1/0.0354

z = 2.8248

z = 2.83

Hence the value of z test is 2.83.

The length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.

It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

The area of the table runner = 80 square inches

Let's assume the length of the rectangle is L and the width is W

Then L = 5×W ...(1)

L×W = 80 ...(2)

Put the value of L in the equation (2)

5W(W) = 80

5W² = 80

W² = 16

W = ±4

Width cannot be negative.

W = 4 inches putting this value in the equation (1)

L = 5(4) = 20 inches

Thus, the length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.

Answer: 9.

Step-by-step explanation: To find the MAD (mean absolute deviation) we need to do the following steps below:

1. Find the mean.

2. Subtract the mean from the numbers of the data.

3. Add the results and divide to find the MAD.

The steps are done below:

1. Find the mean: In order to find the mean of a data set, you need to add all the numbers and then divide the result by how many numbers there are in the data set.  In this problem, there are 10 numbers in the data set, so whatever we get for adding the data numbers together needs to be divided by 10.

2. Subtract the mean from the numbers of the data: To do this, we need to subtract 33 from all the numbers on the data.  The following is done below. (*Note: You may notice that most equations like 26 - 33 would be in the negatives, but for data, it has to be positive.  If you ever run into a situation like that, you simply just make it positive).

3. Add the results and divide to find the MAD: Now that we have the results, we add those numbers and then divide to find the MAD.  Make sure that when you divide that it is 10 that you're dividing because once again, there are 10 numbers for the results.

Therefore, 9 is the MAD.

13 cm = AC

b) Applying Pythagorean theorem to triangle ACD, and solving for AD:

CD² + AC² = AD²

5² + 13² = AD²

√194 = AD

Answer:

z1 - 2z = 2

Step-by-step explanation:

make 2i stand alone in both equations

therefore, in equation one, we have;

z1-5=-2i

5-z1=2i

we do same in equation 2

z2-3=2i

therefore, comparing the two equations, we can equate them!

2z-3=z1-5

-3+5=z1-2z

2 = z1 - 2z

therefore, z1 - 2z = 2

A mean is an arithmetic average of a set of observations. The value of the unknown number is 16.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Let the unknown number be represented by x.

As per the formula of averages, we can write,

Mean = (Sum of observations)/Number of observations

(7 + 8 + 21 + 33 + x)/5 = 17

(69 + x) / 5 = 17

Multiply both the sides of the equation by 5,

(69 + x)/5 × 5 = 17 × 5

69 + x = 85

Subtract 69 from both the sides of the equation,

69 + x - 69 = 85 - 69

x = 16

Hence, the value of the unknown number is 16.
