Answer:

a) Opposite sides are congruent and all interior angles are right angles, hence the quadrilateral is a rectangle

b) Opposite sides are parallel and all sides are congruent, hence the quadrilateral is a rhombus

c) All sides are congruent and all interior angles are right angles, hence the quadrilateral is a square

d) m∠AEB = 90° as the diagonals are perpendicular to each other

e) m∠EAD = 90°/2 = 45° as the diagonals of a square are bisectors of the angles at the vertices

Answer:

5c^2+2cd-2d^2-15

Step-by-step explanation:

Hello, to find the perimeter of any shape, you just add all the side together. In this picture, you would add all the sides up like this:

4c^2+4cd+12+-5d^2-5cd+2+c^2-d^2+1+3cd+4d^2-30

Then, combine like terms (add all of the numbers with the certain variable together) and you would get the answer which is:

5c^2+2cd-2d^2-15

Given figure is Parallelogram:

Answer of 7:HK=JI(Given;since in a parallelogram opposite sides are equal and parallel always given)

Answer of 8:JH=JH(common side of both the traingles)

Answer of 9:(By SSS axiom of congruency).

Answer:

50.24

Step-by-step explanation:

a=(pi)r²

A =(pi)4²

A = 50.27

but I used the actual pi if you use 3.14 I think you'll get 50.24 but that's the closest answer.

Hope you get it right

Answer:

1,206 ft

Step-by-step explanation:

6/4 = 1.5   ( proportion 1.5)

804(1.5) = 1,206

Answer:

about 63.59 ft squared

Step-by-step explanation:

9/2 = 4.5--> Radius

Now we use the Area formula: piR^2 (Pi x radius squared)

4.5^2 = 20.25

20.25 x 3.14 = 63.59 -(rounded answer)

The sum of the numbers 13 + 13 + 13 is 39.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given expression is,

13 + 13 + 13

Here 13 is added to itself three times.

When 13 added to 13, we get 13 + 13 = 26

Again if we add the number 13 to 26, we get 13 + 26 = 39

13 + 13 + 13

= 26 + 13

= 39

This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.

Hence the number 13 added to itself three times gives 39.

Answer:

6.5cm

Step-by-step explanation:

please find attached the question

the length of the apothem can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 9.4/2 = 4.7cm

c =  hypotenuse = 8cm

a² + 4.7² = 8²

a² + 22.09 = 64

a² = 41.91

find the square root

a = 6.5 cm

Given:

Consider the given gallons are [tex]8\dfrac{1}{4}[/tex] gallons.

To find:

The number of quarts in [tex]8\dfrac{1}{4}[/tex] gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

[tex]8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}[/tex]

[tex]8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}[/tex]

Therefore, there are 33 quarts in [tex]8\dfrac{1}{4}[/tex] gallons.
