Since you are in middle school, I will assume simple shapes such as rectangles and squares

area=legnth times width
therefor
width=area/legnth and
legnth=area/width

Answer:

106 m^2

Step-by-step explanation:

First multiply the shaded area:

12 * 10 = 120

Then multiply the white space:

7 * 2 = 14

Then subtract the white space from the shaded area to find the area of only the shaded area.

120 - 14 = 106

Final answer: 106 m^2

I hope this helps!

What pattern is represented by the polynomial ?

Ymorist [56]

Answer:

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial $4x^2+12x+9$ .

To find that pattern, we need to factor $4x^2+12x+9$

$4x^2+12x+9$

$=4x^2+6x+6x+9$

$=2x(2x+3)+3(2x+3)$

$=(2x+3)(2x+3)$

$=(2x+3)^2$

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

Find the solution(s) to 22 +57-3 = 0. Check all that apply.

irakobra [83]

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

$x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}$

$x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}$

$x = \frac{-5 \pm 7}{4}$

$x_1 = \frac{-5 + 7}{4}$

$x_1 = 0.5$

$x_2 = \frac{-5 - 7}{4}$

$x_2 = -3$

The data set shown below represents the number of times some families went out for dinner the previous week. 4, 2, 2, 0, 1, 6, 3

Mkey [24]

Dot plots are used to represent data using dots

The true statements about the dataset are:

The range of the number line should be 0 to 7 to represent the frequency.
Four families said they ate out twice the previous week.
One family said they ate out 5 times the previous week

The dataset is given as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

Rearrange in ascending order

0, 0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6

Represent as a frequency table

Data Frequency

0 2

1 2

2 4

3 0

4 2

5 1

6 1

See attachment for the dot plot

From the attachment, we can see that:

4 has a frequency of 2
5 has a frequency of 1

Also, the range on the dot plot can be 0 to 7, because it covers the given dataset

Hence, the true statements are: (a), (b) and (c)
