First you need to solve for x by subtracting 9 from both sides (-3x less than/equal to 6), then dividing the inequality by -3, which would also flip the sign, so to speak. now you would have x is greater than/ equal to -2. now you would draw a circle above -2, fill it in since it is equal to, and draw the arrow going toward 0 (I think)

What is the pythetherom
pashok25 [27]

Answer:

The Pythagorean Theorem states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).  

The Pythagorean theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:  

a2 + b2 = c2

Ede4ka [16]

Answer:

The actual area of the garden is 1256 square feet.

Step-by-step explanation:

Given:

A gardener is designing a circular garden.

On the blueprint, the garden has a diameter of 16 centimeters.

The blueprint has a scale of two centimeters to five feet.

Now, to find the actual area of the garden.

Let the actual diameter of the garden be x\ feet.

And the diameter of the garden on blueprint = 16\ centimeters.

As, given:

The blueprint has a scale of two centimeters to five feet.

2 centimeters is equivalent to 5 feet.

Thus, 16 centimeters is equivalent to x\ feet.

Now, to get the actual diameter by using cross multiplication method:

\frac{2}{5} =\frac{16}{x}

By cross multiplying we get:

2x=80

Dividing both sides by 2 we get:

x=40\ feet.

<em>Thus, the actual diameter of the garden is 40 feet.</em>

Now, to get the area of the garden we get the radius and then put the formula of area:

Radius = \frac{Diameter}{2}

Radius(r)= \frac{40}{2}=20\ feet.

Area =\pi r^2.

Area=3.14\times 20^2

Area=3.14\times 400

Area=1256\ square\ feet.

Therefore, the actual area of the garden is 1256 square feet.
