Answer:
40cm^2
perimeter:24cm
Step-by-step explanation:
Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.
Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

ABCD is a quadrilateral with A(8,21),B(10,27),C(26,26) and D(18,2). Determine whether ABCD is a trapizoid
ABCD is a trapezoid
Step-by-step explanation:Given points of the quadrilateral:
A(8,21),B(10,27),C(26,26) and D(18,2)
To show whether ABCD is a trapezoid, we find a pair of parallel sides in ABCD. If two of its sides are parallel to each other then ABCD is a trapezoid.
Step 1: With the given points, sketch a graph. The diagram is attached to this response.
Step 2: As shown in the diagram, the two sides that are likely to be parallel are AB and CD
If these two sides have same gradient/slope, then the quadrilateral is a trapezoid.
Now calculate the slopes of those sides using the slope formula;
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Calculate the slope of AB (where x₁ = 8, y₁ = 21, x₂ = 10, y₂ = 27)
m(AB) = [tex]\frac{27-21}{10-8}[/tex]
m(AB) = [tex]\frac{6}{2}[/tex]
m(AB) = 3
Calculate the slope of CD (where x₁ = 26, y₁ = 26, x₂ = 18, y₂ = 2)
m(CD) = [tex]\frac{2-26}{18-26}[/tex]
m(CD) = [tex]\frac{-24}{-8}[/tex]
m(CD) = 3
Since the two slopes - m(AB) and m(CD) slopes are equal to 3, the quadrilateral ABCD is a trapezoid.

What is the value of X in the equation x²-6x+9=25
Answer:
X = -2 or X = 8
Explanation:
Please find the missing side and show your work:)
Answer:
The answer is 5.66
Step-by-step explanation:
let the missing side be x
9² = 7² + x²
9² - 7² = x²
x² = 9² - 7²
x² = 81 - 49
x² = 32
x = √32

A deli orders ham and turkey. The ratio of the number of ham slices to the number of turkey slices is 2:3. What is the ratio of the number of turkey slices to the total of ahem and turkey slices
Answer:
3 :5
Step-by-step explanation:
A deli orders ham and turkey.
The ratio of the number of ham slices to the number of turkey slices is 2:3.
Hence:
Ham slices: Turkey slices
2:3
Sum of proportion = 2 + 3 = 5
Ratio of turkey slices = 3
Ratio of the total of ham and turkey slices = sum of proportion = 5
Therefore, the ratio of the number of turkey slices to the total of ham and turkey slices is

Solve: 2x - 3y = 9 and x + 2y = 1
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )

180-130 = 50
If x and x+ 10 are a pair of adjacent angle find them
Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
If they will be pair of angles on the same line , then their sum will be 180° .=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
Hence the two angles are 85° and 95° .help!! BRAINLIEST TOO!
the data shows the length and weight of a species of fish based on the data
which is closest to the length of a fish that weighs 4.2 pounds
Answer:
36.5 inches
Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Pick any two corresponding points from the table
So, we have:
[tex](x_1,y_1) = (8,1.21)[/tex]
[tex](x_2,y_2) = (12,1.63)[/tex]
So:
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{1.63 - 1.21}{12 - 8}[/tex]
[tex]m =\frac{0.42}{4}[/tex]
[tex]m =0.105[/tex]
The linear equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 0.105 * (x - 8) + 1.21[/tex]
Open bracket
[tex]y = 0.105x - 0.84 + 1.21[/tex]
[tex]y = 0.105x + 0.37[/tex]
To get the length closest to 4.2lb,
we set [tex]y = 4.2[/tex]
Then solve for x
So, we have:
[tex]y = 0.105x + 0.37[/tex]
[tex]4.2 = 0.105x + 0.37[/tex]
Collect like terms
[tex]0.105x= 4.2 - 0.37[/tex]
[tex]0.105x= 3.83[/tex]
Solve for x
[tex]x= 3.83/0.105[/tex]
[tex]x\approx 36.5[/tex]

sin(2x) =
Answer:
NOT 24/25 and NOT -4/5
Step-by-step explanation:
took the quiz
If cos(x) = 3/5 and sin x < 0, sin(2x) is equal to -24/25 as a fraction in simplest terms.
To find sin(2x), we can use the double-angle formula for sine:
sin(2x) = 2 * sin(x) * cos(x)
Given:
cos(x) = 3/5
sin(x) < 0
We need to determine sin(x) based on the given information.
Using the Pythagorean identity, sin^2(x) + cos^2(x) = 1:
[tex](sin(x))^2 + (cos(x))^2 = 1\\(sin(x))^2 + (3/5)^2 = 1\\(sin(x))^2 + 9/25 = 1\\(sin(x))^2 = 1 - 9/25\\(sin(x))^2 = 16/25[/tex]
sin(x) = -4/5
Now we can the values into the double-angle formula for sine:
sin(2x) = 2 * sin(x) * cos(x)
sin(2x) = 2 * (-4/5) * (3/5)
sin(2x) = (-8/5) * (3/5)
sin(2x) = -24/25
Therefore, sin(2x) is equal to -24/25 as a fraction in simplest terms.
