Answer:

6x^2 + 3x + 21 = 3(2x^2 + x + 7)

Step-by-step explanation:

We have this as follows;

6x^2 + 3x + 21 = 3(2x^2 + x + 7)

The quadratic trinomial inside the bracket cannot be factored any further

so we have the present form as the correct answer

Determine The mean,median,mode, and range for each data set A. {2,2,7,9,10}

Zarrin [17]

Answer:

Mean: 6, Median: 7, Mode: 2, Range: 8

Step-by-step explanation:

The mean is the average of the data set.

Add all the terms together:

$2+2+7+9+10=\\4+7+9+10=\\11+9+10=\\20+10=\\\boxed{30}$

Divide the sums by the number of terms:

There are 5 terms in the data set.

$30/5=6$

<h3>Median:</h3>

The median is the middle value of the data set.

The data set given already has the numbers in ascending order.

Seven appears to be in the middle of the set.

{2,2,<u>7</u>,9,10}

<u>The median is 7.</u>

The mode is the number that appears the most in a data set.

The number two appears twice in the data set, and all other numbers (7, 9, and 10) appear once.

<h3>Range:</h3>

The range is the difference between the largest data value in the set and the smallest data value in the set.

In the given set, 10 is the biggest and 2 is the smallest.

10 - 2 = 8

<u>The range is 8. </u>

Inessa [10]

Answer:

E is (1, 2) and M is (-3,-2),

Step-by-step explanation:

G and O are diagonally opposite points.

E is the image of O in the x axis and M is the image of G in the x axis.

E which is adjacent to M and will have y-coordinate of 2 and x -coordinate 1.

M will have x coordinate same as G which is -3 and y coordinate is -2.
