given parallelogram BCDE

what is the equation to find x?
what is x?
what is length of side CD?

please help​

Answer:

\( x = \frac{11}{2} \\ \)

Step-by-step explanation:

f(x) = 2x - 7

when x = 4

It means that equate f(x) to the value of x that's 4 and solve for x

That's

f(x) = 4

We have

\(2x - 7 = 4\)

Add 7 to both sides of the equation

\(2x + 7 - 7 = 4 + 7 \\ 2x = 11\)

Divide both sides by 2

\( \frac{2x}{2} = \frac{11}{2} \\ \)

We have the final answer as

\(x = \frac{11}{2} \\ \)

Step-by-step explanation:

x = total sweets bought

total sweet eaten = x - 4

sweets left = 20

x - 4 = 20

combine like terms

x = 20 + 4

x = 24

The value of x is 1.

On comparison, when two or more triangles have some common relations with respect to their sides or measure of internal angles, they are said to be similar.

To find the value of x, compare the corresponding sides of the two triangles.

Step-by-step explanation:

How many pattern block trapezoids would create for hexagons?

2 trapezoids compose a hexagon using equal-size shapes: 2 trapezoids, 6 triangles, or 3 blue rhombuses. compose hexagons using different shapes. So 2 trapezoids create 1 hexagon. This means 6 trapezoids make 3 hexagons.

The exact number of trapezoids needed to create three hexagons depends on the size and shape of the hexagons.

However, in general, you would need at least 18 trapezoids.

An hexagon is a six-sided polygon. It is made up of six equilateral triangles and six trapezoids.

If you are looking to create larger hexagons you will need more trapezoids.

Depending on the size and shape, you could need as many as 24 or more trapezoids.

An hexagon is a six-sided polygon. It is made up of six equilateral triangles and six trapezoids.

Hence, To create an hexagon using pattern blocks, you need 10 equilateral triangles and 20 trapezoids.

Therefore, to create 5 hexagons.

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

A + B+ C = 180

A +72+ 23 = 180

The Robinson and Friday  jointly consume a maximum of 0 units of grain per week when they produce 16 units of meat.

The second part of the question is 8 units of grain per unit of meat.

To find the maximum units of grain that Robinson and Friday can jointly consume per week when they produce 16 units of meat,  to find the intersection point of their production possibility curves (PPCs).

Robinson's PPC: G = 21 - 7M

Friday's PPC: G = 146 - 8M

Setting both equations equal to each other:

21 - 7M = 146 - 8M

Simplifying the equation:

M = 125

Substituting the value of M back into either equation, let's use Robinson's PPC:

G = 21 - 7(125)

G = 21 - 875

G = -854

Since negative quantities are not meaningful in this context, disregard the negative solution.

To find the admissible terms of trade, to find the slope of their production possibility curves at the point where they consume 16 units of meat.

Taking the derivative of Robinson's production possibility curve equation with respect to M:

dG/dM = -7

Taking the derivative of Friday's production possibility curve equation with respect to M:

dG/dM = -8

The absolute values of these slopes represent the opportunity cost of meat in terms of grain for each person. Therefore, the admissible terms of trade between Robinson and Friday have to be smaller than the absolute value of the steepest slope, which is 8 units of grain per unit of meat.

1. The Perimeter of the base is 32cm

2. The area of the base is 48 cm²

3. Total surface area of the prism is 1184cm²

A prism is a solid shape that is bound on all its sides by plane faces.

Surface area is the amount of space covering the outside of a three-dimensional shape.

The surface area of a prism is expressed as;

SA = 2B +ph

where B is the base area , p is the perimeter of the base and h is the height of the prism.

1. To find the perimeter we need to find the hypotenuse of the base.

x² = 8² +6²

x² = 64+36

x² = 100

x = √100

x = 10 cm

therefore the hypotenuse is 10cm

perimeter = 10+10 +12 = 32 cm

2. The area of the base = 1/2bh

= 1/2 × 12 × 8

= 48cm²

3. The surface area = 2 × 48 + 32 × 34

Since most walls are square or rectangular, their surface area may be calculated by multiplying the width and height values, then taking out any spaces for doors or windows. However, unusual architecture and design might lead to the combination of the rectangle with triangular, round, or trapezoidal shapes. Using the fundamental formulas for estimating the area of two-dimensional forms is the key to accurately determining the surface area of a wall.

the height of the triangle formed by the diagonal and base of the TV screen.

The height of the TV is approximately 15.6 inches.

(26 inches / √2) = 18.8 inches

(18.8 inches * √2) = 26 inches

Height = (26 inches / 18.8 inches) * 18.8 inches

Height = 15.6 inches

Step 1: Calculate the hypotenuse of the triangle formed by the diagonal and base of the TV screen.

Hypotenuse = diagonal / √2

Hypotenuse = 26 inches / √2

Hypotenuse = 18.8 inches

Step 2: Calculate the diagonal of the triangle formed by the hypotenuse and base of the TV screen.

Diagonal = hypotenuse * √2

Diagonal = 18.8 inches * √2

Diagonal = 26 inches

To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.

If 12 workers can complete a building project in 54 days, to determine this we can divide the rate of work by the number of workers by the number of days: 12 workers / 54 days = 0.2222 workers/day.

If the construction manager wants to complete the project in 36 days, he needs to increase the rate of work to complete the project in that shorter timeframe. To do this, he can add more workers or increase the productivity of the current workers.

To determine how many more workers the manager needs, we can use the formula:

(number of workers) = (rate of work) x (number of days)

By plugging in the desired rate of work and number of days, we get:

(number of workers) = (0.2222 workers/day) x (36 days) = 7.999 workers

a. To find the vertex of the quadratic function f(x) = \(x^2 - 4x + 3\), we can use the formula \(x = -b/2a\). In this case, a = 1 and b = -4. Plugging these values into the formula, we get x = \(-(-4)/(2*1) = 4/2 = 2\). Therefore, the vertex is (2, f(2)).

b. The equation of the axis of symmetry is given by x = h, where h is the x-coordinate of the vertex. In this case, h = 2. Therefore, the equation for the axis of symmetry is x = 2.

c. To find the range of the quadratic function, we need to determine the minimum or maximum value of the function. Since the coefficient of the \(x^2\) term is positive, the parabola opens upwards and the vertex represents the minimum point.

Therefore, the range of the function is all real numbers greater than or equal to the y-coordinate of the vertex. In this case, the range is y ≥ f(2). By substituting x = 2 into the function,

we get f(2) = \(2^2 - 4(2) + 3 = 4 - 8 + 3 = -1\). Therefore, the range is y ≥ -1.
