The calculated area of the composite figure is 85 cm².

From the question, we have the following parameters that can be used in our computation:

The composite figure (see attachment)

Where, we have

Rectangle:

Area = length × width.

Therefore, the area of the rectangle is 10 cm × 6 cm = 60 cm².

Triangle:

Area = (1/2) × base × height.

Therefore, the area of the triangle is (1/2) × 5 cm × 10 cm = 25 cm².

To find the total area of the composite figure, we add the areas of the rectangle and the triangle:

Total Area = Area of Rectangle + Area of Triangle

= 60 cm² + 25 cm²

= 85 cm².

Therefore, the area of the composite figure is 85 cm².

Step-by-step explanation:

the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

what is rectangle?

A rectangle is a four-sided polygon with opposite sides that are parallel and equal in length.

Let's denote the width of the garden by x. Then, according to the problem statement, the length of the garden is x + 5.

The total width of the garden and the walkway is x + 2(3) = x + 6, and the total length is x + 5 + 2(3) = x + 11.

The area of the garden itself is x(x + 5), and the area of the garden and the walkway is (x + 6)(x + 11).

The area of the walkway is the difference between the two: (x + 6)(x + 11) - x(x + 5) = 210.

Expanding and simplifying this expression, we get:

x^2 + 17x - 135 = 0

We can solve for x using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = 17, and c = -135, so we have:

x = (-17 ± sqrt(17^2 - 4(1)(-135))) / 2(1)

x = (-17 ± sqrt(769)) / 2

We can discard the negative solution, so we have:

x = (-17 + sqrt(769)) / 2

x ≈ 6.77

Therefore, the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

Answer:

  (x, y) = (-7, 5)

Step-by-step explanation:

I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...

  (x, y) = (-7, 5)

__

In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.

  (4x -6y) -(-2x -6y) = (-58) -(-16)

  6x = -42 . . . . . . . . . simplify

  x = -7 . . . . . . . . divide by 6

Substituting into the first equation gives ...

  -2(-7) -6y = -16

  6y = 30 . . . . . . . . . . add 16+6y to both sides

The Expression x^2 - 6x + 9 when x = 2 + i   is -2i

To evaluate the expression x^2 - 6x + 9 when x = 2 + i, we substitute the value of x into the expression:

(2 + i)^2 - 6(2 + i) + 9

Simplifying the first term, we get:

(2 + i)^2 = 2^2 + 2(2)(i) + i^2 = 4 + 4i + i^2

Since i^2 = -1, we can substitute that in and simplify further:

(2 + i)^2 = 4 + 4i - 1 = 3 + 4i

Now we substitute this into the original expression:

(2 + i)^2 - 6(2 + i) + 9 = (3 + 4i) - 6(2 + i) + 9

Simplifying further, we get:

= 3 + 4i - 12 - 6i + 9

= 0 - 2i

= -2i

Therefore, the value of x^2 - 6x + 9 when x = 2 + i is -2i.

As ratio is not given, we cannot prove that they are scaled copy.

Corresponding portions, or parts that are at the same location in relation to the remainder of each figure, exist in both the original figure and its scaled copy. These components could be angles, points, or segments. Polygon 2, for instance, is a scaled-down version of Polygon 1. There is a point in Polygon 2 for each point in Polygon 1.

Given,

Polygon ZSCH is a Scaled copy of Polygon XJYN.

We simply calculate the ratio of the lengths of the two corresponding sides of two polygons to determine the scale factor. The scaling factor is known as such and the polygons are similar if the ratio is the same for all matching sides.

As ratio is not given, we cannot prove that they are scaled copy.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

x = 0

Step-by-step explanation:

From the intersecting secants theorem, If from an exterior point, we draw two secant segments to a circle, then the product of the length of one secant segment and its external secant part will be equal to the product of the length of the other secant segment and its external secant portion.

Thus, applying it to this question;

(x + 27 + 48) × (x + 27) = (x + 45)²

(x + 75)(x + 27) = x² + 90x + 2025

x² + 102x + 2025 = x² + 90x + 2025

Like terms will cancel put to give;

102x - 90x = 0

12x = 0

x = 0/12

x = 0

Answer:

C

Step-by-step explanation:

Let's set up a simultaneously equation to solve for two unknows.

Let x be the cost of cheese pizza

Let y be the cost of mushroom pizza

"Jack bought 3 slices of pizza and 4 slices f mushroom pizza for a total cost of $12.50."

Therefore,

3x + 4y = 12.50 (Equation 1)

"Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of 8.50."

Therefore,

3x + 2y = 8.5 (Equation 2)

From equation 1, let's solve for x in terms of y

3x + 4y = 12.50

3x = 12.50 - 4y

\(y = \frac{12.50-4y}{3}\)

Plug in this y value into equation 2, we have:

\(3(\frac{12.50-4y}{3}) + 2y = 8.5\)

We will get that y = 2

Hence, option C is the answer.

Answer:

There are 14 horses and 21 chickens.

Step-by-step explanation:

First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :

\(4x + 2y = 98\)

( horse has 4 feet and chicken has 2 feet )

There are a total of 35 heads so the other equation will be :

\(x + y = 35\)

Lastly, you have to solve it :

\(4x + 2y = 98\)

\(2(2x + y) = 98\)

\(2x + y = 49 - - - (1)\)

\(x + y = 35 - - - (2)\)

\((1) - (2)\)

\(2x + y - x - y = 49 - 35\)

\(x = 14\)

\(substitute \: x = 14 \: into \: (2)\)

\(14 + y = 35\)

\(y = 35 - 14\)

\(y = 21\)

solve the equations

a) replace the x value from equation (2) into equation (1) and solve for y

b) now, replace the y value into equaiton (2) to find the x value
