Answer:

the answer is 9.

Step-by-step explanation:

First you do what is in the "( )".

(6-3)^2 = 3^2

Now after you do that you have to square the sum you have. Now you know that when you square you time the number by what the number is.

3^2 = 3x3 = 9

That is the answer.

Hope it helps!!!

Your Welcome,

Polygon CCC has an area of 404040 square units. K 2ennan drew a scaled version of Polygon CCC using a scale factor of \dfrac12 1
nikdorinn [45]

Answer:

<em>Area of polygon D = 10 square units</em>

Step-by-step explanation:

<u>Given:</u>

Polygon <em>C </em>has an area of 40 square units.

It is scaled with a scale factor of \frac{1}2 to form a new polygon D.

<u></u>

<u>To find:</u>

The area of polygon D = ?

<u>Solution:</u>

When any polygon is scaled to half, then all the sides of new polygon are half of the original polygon.

And the area becomes one-fourth of the original polygon.

Let us consider this by taking examples:

  • First of all, let us consider a right angled triangle with sides <em>6, 8 and 10 units.</em>

Area of a right angled triangle is given by:

A = \dfrac{1}{2} \times Base \times Height\\\Rightarrow A = \dfrac{1}{2} \times 6 \times 8 = 24\ sq\ units

If scaled with a factor \frac{1}{2}, the sides will be 3, 4 and 5.

New area, A':

A' =\dfrac{1}{2} \times 3 \times 4 = 6\ sq\ units = \dfrac{1}4\times A

i.e. Area becomes one fourth.

  • Let us consider a rectangle now.

Sides be 8 and 10 units.

Area of a rectangle, A = Length \times Width = 8 \times 10 = 80 sq units.

Now after scaling, the sides will be 4 and 5 units.

New Area, A' = 4 \times 5 =20 sq units

So, \bold{A' = \frac{1}4 \times A}

Now, we can apply the same in the given question.

\therefore Area of polygon D = \bold{\frac{1}{4}}\times Area of polygon C

Area of polygon D = \bold{\frac{1}{4}}\times 40 = <em>10 sq units</em>

The perimeter of an equilateral triangle is 1/8 unit. What is the length, in units, of each side of the triangle
svp [43]
<h2>The length of each side of the equilateral traingle is 1/24 unit.</h2>

<u>Step-by-step explanation:</u>

Given that the perimeter of an equilateral triangle is 1/8 unit. With this information, we are asked to find the length of each side of yhe equilateral traingle.

The perimeter of equilateral traingle is defined as the three times of the length of edge. Mathematically;

→ Perimeter = 3a

By substituting the given values in the formula, we get the following results:

→ 1/8 = 3a

→ a = 1/24

Hence, the length of each side of the equilateral traingle is 1/24 unit.

<u>Additional information:</u>

  • A triangle has three sides or edges.
  • A triangle has three angles.
  • A triangle has three vertices or corners.
  • The sum of all internal angles of a triangle is always equal to 180 degrees. This is known as the angle sum property of a triangle.
  • The sum of the length of any two sides of a triangle is greater than the length of the third side.
  • There are three types of triangle, Scalene Triangle, Isosceles Triangle, Equilateral Triangle.
  • Area of triangle = 1/2 * b * h.
  • Perimeter of triangle = sum of all sides.
