-3 + 6x. Which expression shows the correct factorization?
Here are the ones to pick from
1. -2 + -2 +6 +x
2. 6(-2 +x)
3. 6(-2 +x)
4. -3 (1 - 2x)

Answers

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

Simplify −3√27−2√2−3√45−√18 Work Needed

Answers

Answer:

Step-by-step explanation:

27 = 3 * 3 * 3

-3√27 = -3*3√3 = -9√3

Index of the radical is 2. So, after prime factoring, for each two of same number, pull one outside.

-3√45= -3√3*3*5 = -3*3√5 = -9√5

-√18 = -√2*3*3 = -3√2

-3√27 - 2√2 - 3√45 - √18 = -9√3 - 2√2 -9√5 -3√2

Now combine like terms

         = -9√3 - 9√5 -2√2 - 3√2

        = -9√3 - 9√5 - 5√2

Answer:

-9√3 - 5√2 - 9√5

Step-by-step explanation:

-3√27 = -3√9x3 = -3x3√3 = -9√3

2√2 = 2√2

3√45 = 3√9x5 = 3x3√5 = 9√5

√18 = √9x2 = 3√2

-9√3 - 2√2 - 9√5 - 3√2 = -9√3 - 5√2 - 9√5

What is a Quadrilateral?

A quadrilateral is a polygon with four sides.

The quadrilateral ABCD is divided into 2 triangles by its diagonal

The area of Quadrilateral will be equal to the sum of the area of tho scalene triangles

The area of a scalene triangle is given by

\(\rm A = \sqrt{s (s-a)(s-b)(s-c)\)

s is the semi perimeter = (a+b+c)/2

The sides of the Triangle ADC is 3.54, 17.29, 17.21

and The sides of the Triangle ABD is 7.84, 17.29, 9.59

s for ADC = (3.54+17.29+17.21)/2 = 19.02

Jorge invested a total of $5000. He invested some of his money at 4% and the rest at 7%. If the total return at the end of the year was $320, how much was invested at each rate?

Answers

Step-by-step explanation:

Let's solve this problem using a system of equations.

Let's assume that Jorge invested x dollars at 4% interest and (5000 - x) dollars at 7% interest.

The interest earned from the 4% investment can be calculated as (4/100) * x.

The interest earned from the 7% investment can be calculated as (7/100) * (5000 - x).

According to the problem, the total return at the end of the year was $320. Therefore, we can set up the following equation:

(4/100) * x + (7/100) * (5000 - x) = 320

Simplifying and solving for x:

(4/100) * x + (7/100) * 5000 - (7/100) * x = 320

0.04x + 0.07(5000 - x) = 320

0.04x + 350 - 0.07x = 320

-0.03x = -30

x = -30 / -0.03

x = 1000

Jorge invested $1000 at 4% interest and the remaining amount, $5000 - $1000 = $4000, at 7% interest.

Therefore, Jorge invested $1000 at 4% and $4000 at 7%.

A) Elise needs 7 quarts of ice cream
B) Elise needs 6 quarts of ice cream.
C) The constant of proportionality is 1 /6.
D) The constant of proportionality is 6/ 1.
E) The constant of proportionality is 1/ 8.

Answers

Answer:

A (Elise needs 7 quarts of ice cream)

Step-by-step explanation:

Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.

Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.

So 42 people divided by 6 equals 7 quarts.

Answers

Answer:

y=72

x=53

there are 72 packages

Step-by-step explanation:

3.5x+2.25y=347.5

x+y=125

Thereby y=125-x

so

3.5x+2.25(125-x)=347.5

3.5x-2.25x+281.25=347.5

1.25x=66.25

x=53

53+y=125

y=72

Answer:

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!

Answers

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.

2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.

3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.

4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).

5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.

6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.

7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

\(\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}\)

♥️ \(\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}\)

To create a box plot for this data set, we need to find the minimum value, maximum value, median, and quartiles.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38

The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.

In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.
