Answer:
The correct answer is 1 for the first part, and 12n+8 for the second part.
Step-by-step explanation: I got them wrong for you guys. Edge 2021.
The product of the expression given is 12n + 8.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is ([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4)
Multiplying the numerators together,
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (9n² - 4)] / [6n - 4]
= {8 [ (3n)² - (2)² ] } / {6n - 4}
We have an algebraic identity, a² - b² = (a + b) (a - b)
Using this identity (3n)² - (2)² = (3n + 2) (3n - 2)
And the expression in the denominator, 6n - 4 = 2 (3n - 2)
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (3n + 2) (3n - 2)] / [2 (3n - 2)]
The expression 3n - 2 gets cancelled as it lies in both numerator and denominator.
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8(3n + 2)] / [2]
= 4 (3n + 2)
= 12n + 8
Hence the product is 12n + 8.

Answer:
9
Step-by-step explanation:
The given two triangles must be similar by AA similarity Condition . Therefore ,
∆EDA ~ ∆ CBA .And the corresponding sides of the similar triangles are Proportional . Therefore ,
⇒ ED/ CB = AD/AB
⇒ 11/2 = 3 + x / 3
⇒ 33 = 2(3+x)
⇒ 6 + 3x = 33
⇒3x = 33 - 6
⇒ 3x = 27
⇒ x = 27/3
⇒ x = 9
Hence the value of x is 9 .2^2018+2^2019-2^2020/2^2020-2^2021-2^2022

Ordena los términos del 1 al 5, de tal manera que
cada término se construya del término (s) anterio
Explica por qué cada figura está en el lugar que
eliges. Los términos son: cuadrilátero, cuadrado
rombo, rectángulo y paralelogramo
Answer:
El orden es;
1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado
Step-by-step explanation:
Los términos dados son;
Cuadrilátero; Una forma con cuatro lados
Rombo; Un cuadrilátero con cuatro lados iguales
Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos
Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos
Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos
Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término
Por lo tanto, tenemos,
La primera forma es el cuadrilátero,
El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)
El ángulo del rombo se ajusta para dar un paralelogramo
El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo
El rectángulo se ajusta para dar un cuadrado con todos los lados iguales

Samantha and her children went into a grocery store and she bought $7 worth of bananas and peaches. Each banana costs $0.40 and each peach costs $0.50. She bought a total of 15 bananas and peaches altogether. Determine the number of bananas and the number of peaches that Samantha bought.
Answer:
Ten Peaches and five bananas.
Step-by-step explanation
To solve the problem increase the cost by adding more peaches and less by adding more bananas
7 peaches = 3.50
8 bananas = 3.20 + 3.50 = 6.70
We need 30 more cents so add three more peaches
10 peaches = 5
5 x 0.4 = 2
2 + 5 = 7
An angle measures 32° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
First angle = x
Second angle = x - 32
We know that, complementary angles form => 90°
So,
[tex]x + x - 32= 90 \\ 2x = 90 + 32 \\ 2x = 122 \\ x = \frac{122}{2} \\ x = 61[/tex]
First angle,
=> x = 61°
Second angle
[tex]x - 32 \\ = 61 - 32 \\ = 29[/tex]
Second angle,
=> 29°

,=> area = (22/7)*6*6
=> area = 113.04 insq
=> area of sector =( πr^2*8°)/360°
=> area of sector = 2.51 insq

Find the measure of the indicated arc
Step-by-step explanation:
We know that if an arc subtends an angle of theta , with a radius r , then the measure of arc is r× theta . Here theta is 109° .
[tex]\implies l = r\theta \\\\\implies l = r\times 109^{\circ}\\\\\implies l = r \times \dfrac{109}{180}\pi rad \\\\\implies \boxed{\boxed{ l = 0.6\pi r m }}[/tex]
where r will be the radius .

Find the surface area of the figure below.
Answer:
696.8 mm^2
Step-by-step explanation:
Well first lets find the bottom part of the square first.
13*13= 169
Thats the floor
13*5= 65
Thats 1 of the sides
there are 4 sides
65*4= 260
260+169= 429
Now find the triangle
(13*10.3) / 2
You’d get 66.95
66.95 *4 since there are 4 sides
You’d get 267.80
267.8+429= 696.8
Which measurements could not represent the side lengths of a right triangle?
A 6 cm, 8 cm, 10 cm
B В
12 cm, 35 cm, 37 cm
C 4 cm, 6 cm, 10 cm
10 cm, 24 cm, 26 cm
Answer: C
Step-by-step explanation: a^2 + b^2 = c^2
A. 6^2 + 8^2 = 10^2
B. 12^2 + 35^2 = 37^2
C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52 10^2 = 100)
D. 10^2 + 24^2 = 26^2
The measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
For the triangle sides:
6 cm, 8 cm, and 10 cm
From the Pythagoras theorem:
[tex]10^2=8^2+6^2[/tex]
100 = 100
These sides satisfy the Pythagoras formula.
For the triangle sides:
12 cm, 35 cm, and 37 cm
From the Pythagoras theorem:
[tex]37^2=35^2+12^2[/tex]
1369 = 1369
These sides satisfy the Pythagoras formula.
For the triangle sides:
4 cm, 6 cm, and 10 cm
From the Pythagoras theorem:
[tex]10^2=6^2+4^2[/tex]
100 ≠ 52
These sides do not satisfy the Pythagoras formula.
For the triangle sides:
10 cm, 24 cm, and 26 cm
From the Pythagoras theorem:
[tex]26^2=24^2+10^2[/tex]
676 = 676
These sides satisfy the Pythagoras formula.
Thus, the measures of the triangles 4 cm, 6 cm, and 10 cm do not represent a right angle triangle because it does not follow the Pythagoras theorem option (C) is correct.

Answer:
The values of x and y are 23.83 and 31.1.
Step-by-step explanation:
Given that,
Perpendicular = 20 units
Angle, [tex]\theta=40^{\circ}[/tex]
We need to find the values of x and y.
Using trigonometry,
[tex]\tan(40)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(40)}\\\\x=23.83[/tex]
To find y use Pythagoras theorem,
[tex]y^2=23.83^2+20^2\\\\y=31.1[/tex]
So, the values of x and y are 23.83 and 31.1.
