Factorise 3(a-b)(3r-T)+9(b-a)(2t-5s)
The factorization of the given expression 3(a-b)(3r-T)+9(b-a)(2t-5s) will be equal to 3(a-b){[3r-T]-392t-5s]}.
What is an expression?Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Given expression is 3(a-b)(3r-T)+9(b-a)(2t-5s) the factorization will be done as below:-
E = 3(a-b)(3r-T)+9(b-a)(2t-5s)
E = 3(a-b)(3r-T)- 9(a-b)(2t-5s)
E = 3(a-b){[3r-T]-392t-5s]}.
Therefore, the factorization of the given expression 3(a-b)(3r-T)+9(b-a)(2t-5s) will be equal to 3(a-b){[3r-T]-392t-5s]}.

Using the sine ratio, the value of x is: A. 26°.
How to Apply the Sine Ratio?Sine ratio is:
Sin ∅ = opposite side length / hypotenuse length of a right angle.
Given the following:
Reference angle (∅) = x
Opposite side length = 11
Hypotenuse side length = 25
Plug in the values
Sin x = 11/25
x = sin^(-1)(11/25)
x ≈ 26°

What is the simplified form of 2+i / 2-i ?
(A) -1 (B) 3+4i/3 (C) 5+4i/5 (D) 3+4 i/ 5
The simplified form of (2 + i)/(2 - i) is (3 + 4i)/5
A Simple Form or simplified form can be defined as When a fraction's numerator and denominator share only one common factor, it is said to be in its simplest form.
Consider the given complex number(2 + i)/(2 - i)
Multiply both numerator and denominator with the complex number (2 + i), and we get
{(2 + i) × (2 + i)} / {(2 + i) × (2 - i)}= {(2 + i) × (2 + i)} / (2² - i²)
(using the formula (x + y)(x - y) = x² - y²)= {(2 + i) × (2 + i)} / (4 - (-1))= {(2 + i) × (2 + i)} / (4 + 1)= {(2 + i) × (2 + i)} / 5= (2² + 2i + 2i + i²)/5= (4 + 4i + (-1))/5= (3 + 4i)/5

If you can fit 19 people in a 5ft x 5ft square, how many people would fit along a parade route, 10ft deep on each side of the street and one mile long?
There are 40128 peoples in the parade route by proportion.
According to the given question.
You can fit 19 people in a 5ft x 5ft square.
Here we need to find the number of peoples in the 10ft x 1 mile parade.
Since, we have to convert miles into feet then,
1 mile = 5280 feet
We know that the parade route is in the form of rectangle.
Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.
Now we will find the number of peoples by proportions,
Let us consider the number of people in the rectangle as x.
Therefore,
19/25 = x/5280
⇒ (19/25)(5280) = x
⇒ x = 40128
Hence, there are 40128 peoples in the parade route by proportion.

Using a letter to represent the unknown number, select the equation that matches the problem.
A stick is 5 m long. A rope is 4 times as long as the stick. If the rope is divided into 2 pieces, how many meters long is each piece of rope?
The length of each piece of rope is 10m.
What is the length of each peace of rope?The first step is to determine the length of the rope before it was cut. In order to determine the length of the rope, multiply the length of the stick by the number of times the rope is as long as the stick.
Multiplication is the process that is used to determine the product of two or more numbers. The sign that is used to represent multiplication is x.
Length of the rope = length of the stick x 4
4 x 5 = 20m
lf the length of the rope is divided into two prices, divide the length of the rope by 2. Division is the mathematical operation that is used to determine the quotient of two or more numbers. It entails grouping a number into equal groups using another number.
Length of each piece = Length of the rope / 2
20m / 2 = 10m

Find (g • h)(n)
The equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
g(n) = -4n - 4
h(n) = n² +5+n
(g • h)(n) = g(n)h(n)
= (-4n - 4)(n² +5+n)
= -(4n + 4)(n² +5+n)
After simplification:
(g • h)(n) = -4n³ - 8n² - 24n - 20
Thus, the equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.

The answer of the following fraction which involves ABC is said to be 12:20:25
The transformation of a ratio into a fraction is known as the simple fraction form. In order to convey the relative size of two or more variables, the ratio is utilized. The fraction similarly identifies the components of the total. A:B or a/B are two ways to represent the ratio. As an illustration, the ratio is 12: 15.
Express the ratio in terms of a
a/b = 3/5 (cross-multiply)
3b = 5a (Divide the total both sides by 3)
b= 5/3 a
b/c = 4/5 (cross-multiply)
4c = 5b (divide the total both sides by 4)
c= 5/4 b=5/4×5/3 a=25/12a
then
a:b:c
=a:5/3 a:25/12 a (multiply each part by 12 to clear the fractions)

The perimeter of a rectangle is 102 feet. Find the length and width if the length is an integer and the width is 3 times the next consecutive integer.
Length = [_] feet
Width = [_] feet
The length of the rectangle is 12feet and the width is 26feet.
Perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed according to the equation below:
Perimeter = 2(length + width)
If the width is 3 times the next consecutive integer, then;
w = 3(x+1)
l = x
Substitute
102 = 2(x + 3x + 3)
102 = 2(4x + 3)
102/2 = 4x+ 3
51 = 4x + 3
4x = 48
x = 12 = length
For the width
width = 2(x+1)
width = 2(12+1)

Question: 18 The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. Suppose that the drama club has a goal of making $3400 each night of their spring play to cover expenses and raise money for the club. Adult tickets are $7 and students/senior tickets are $4.
Based on the information, it should be noted that there be 67 adults and 733 students in the auditorium.
How to calculate the value?Let adults tickets = a
Let students tickets = s
The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. This will be:
a + s = 800 ..... i
Therefore, suppose that the drama club has a goal of making $3400. This will be:
7a + 4s = 3400 ..... ii
From equation i, a = 800 - s.
7a + 4s = 3400
7(800 - s) + 4s = 3400
5600 - 7s + 4s = 3400
Collect like terms
-7s + 4s = 3400 - 5600
3s = -2200
s = 2200 / 3
s = 733
a = 800 - 733 = 67
Therefore, there'll be 67 adults and 733 students.
