The length of a rectangle is represented by 9x - 5. The width of the rectangle is represented by 3.

Write two equivalent expressions that represent the Area of given rectangle.

Answers

Answer 1

Answer:

First factor the Area

Area = 18x2+12x+2

Factor out a 2

Area = 2(9x2+6x+1)

Factor this and you get

Area=2(3x+1)(3x+1)

Let L be Length and W be Width

Area=LW

and the Length is twice the Width so

L=2W

Area=2(3x+1)(3x+1) so

L=2(3x+1)

W=3x+1

This can also be written as if you distribute the 2

L=6x+2

W=3x+1

(8, 18)
(3, 13)
(20, 10)
(482, 492)

Answers

is there any pic of the graph?

Answer:

(20, 10)

Step-by-step explanation:

y = x + 10

(8, 18)

y = x + 10

18 = 8 + 10

18 = 18 (this point is one the graph)

(3, 13)

y = x + 10

13 = 3 + 10

13 = 13 (this point is on the graph)

(20, 10)

y = x + 10

10 = 20 + 10

10 = 30 (this point is not on the graph)

(482, 492)

y = x + 10

492 = 482 + 10

492 = 492 (this point is on the graph)

The number of marbles of different colors stored in a hat is listed below:


1 red marble

8 green marbles

9 blue marbles

Without looking in the hat, Ray takes out a marble at random. He replaces the marble and then takes out another marble from the hat. What is the probability that Ray takes out a blue marble in both draws?

fraction 1 over 9

fraction 1 over 8

fraction 1 over 4

fraction 1 over 2

Answers

Answer:

1/4

Step-by-step explanation:

1 red marble, 8 green marbles. 9 blue marbles

There are 1+8+9 = 18 marbles

First marble blue

P(blue) = blue / total = 9/18 = 1/2

He replaces the marble so there are still 18 marbles

1 red marble, 8 green marbles. 9 blue marbles

There are 1+8+9 = 18 marbles

Second marble blue

P(blue) = blue / total = 9/18 = 1/2

Multiply the probabilities together

P(blue, replace, blue) = 1/2 * 1/2 = 1/4

Answers

Answer:

y = 3n - 2

Step-by-step explanation:

so to find the slope or rate of change we use the equation

y 2 - y1 / x2 - x1

soo lets use the points

(1, 1) and (2, 4)

4 - 1/ 2 - 1

3/1

3

y = 3n + b

now we substitute a point we did not use yet

(3, 7)

7 = 3(3) + b

7 = 9 + b

b = -2

y = 3n - 2

now check

(4,10)

10 = 3(4) - 2 ?

10 = 12 - 2 ?

10 = 10

Answer:

y = 3n - 2

Step-by-step explanation:

y = mx + b or y = nx + b

Where m or n represents the slope

[tex]m\ or\ n=\frac{y_2-y_1}{x_2-x_1} \\\\m\ or\ n=\frac{4-1}{2-1} \\\\m\ or\ n=\frac{3}{1} \\\\m\ or\ n=3[/tex]

y = 3n + b

(n, y) ==> (2, 4)

y = 3n + b

4 = 3(2) + b

4 = 6 + b

-6 -6

-2 = b

y = 3n - 2

Check your answer using (2, 4):

y = 3n - 2

4 = 3(2) - 2

4 = 6 -2

4 =4

This statement is correct

The width of a rectangle is 7x – 9.5 feet and the length is 9.5x + 10 feet. Find the perimeter of the rectangle.


The answer : perimeter = 33x+1

Answer:

33x + 1

Step-by-step explanation:

Perimeter of a rectangle: P = 2(l + w) OR P = 2(l) + 2(w)length (l) = 9.5x + 10width (w) = 7x - 9.5

P = 2(l + w)

P = 2(9.5x + 10) + 2(7x - 9.5)

P = 19x + 20 + 14x - 19

P = 19x + 14x + 20 - 19

P = 33x + 1

The dot plots below show the scores for a group of students who took two rounds of a quiz:

Two dot plots are shown one below the other. The title for the dot plot on the top is Round 1 and the title for the bottom plot is Round 2. Below the line for each dot plot is written Score. There are markings from 5 to 9 on the line at intervals of one. There are 2 dots above the mark 5, 3 dots above the mark 6, 4 dots above the mark 7, and 1 dot above the mark 8. For the bottom dot plot there are 6 dots above the mark 6, 2 dots above the mark 8, and 2 dots above the mark 9.

Which of the following inferences can be made using the dot plot?

The range of each round is the same.
There is no overlap between the data.
Round 1 scores were higher than round 2 scores.
Round 2 scores were lower than round 1 scores.

Answers

Answer:

The inference that can be made using the dot plot is:

   The range of round 1 is greater than the round 2 range

Step-by-step explanation:

Round 1:

Score                Frequency

 1                          0

 2                          2

 3                          3

 4                          2  

 5                          1

Hence, the minimum score of Round 1 is: 2

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                     =5-2

                      =3

Similarly, Round-2

Score                Frequency

 1                          0

 2                         0

 3                          0

 4                          4  

 5                          4

Hence, the minimum score of Round 1 is: 4

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                     =5-4

                      =1

The scores of round 2 are higher than round-1.

Since round 2 have a higher frequency for higher scores as compared to round-1.

Hence, Range of round 1 is greater than the range of Round-2.

where do y = -x + 8 and y = x - 2 intersect

Answers

Answer:

(5,3)

Step-by-step explanation:

To find where two lines intersect you let them equal to each other.

-x + 8 = x -2

Add 2 on both side

-x + 10 = x

Add x on both sides

10 = 2x

Divide 2 on both sides

5 = x

Now plug x into both equations

y = -5 + 8 = 3

y = 5 - 2 = 3

so y = 3

The point they intersect is (5,3)

What is the area of this figure?

Select from the drop-down menu to correctly complete the statement.

The area of the figure is 'blank' cm².

Answers

Answer:

The area is 146cm squared

Step-by-step explanation:

Starting with the top portion, The formula for the area of a trapezoid is a = (base 1 + base 2) / 2 * h | (14 + 4) /2 *10 = 90.

Now for the bottom part, We know that the height of the top of the figure is 10 and that the overall figure height is 18. To find the height of the triangle at the bottom we would do 18 - 10 = 8.

The formula for finding the area of a triangle is b x h / 2 = a. 14 * 8 / 2 = 56.

Finally, we add our results. 90+56=146.
