The correct option is Option A: The solution of the quadratic equation is x= -4 and 1.
What is the quadratic formula?The quadratic formula is the method for solving and finding the solution of the quadratic equation ax²+bx+c=0.
The solution of the quadratic equation ax²+bx+c=0. by the quadratic formula is given by
x= {-b±√(b²-4ac)}/2a
Here b²-4ac is discriminant denoted by D.
D= b²-4ac
Given the quadratic equation is
x²+3x-4=0
for solving by the quadratic formula
comparing the above equation by ax²+bx+c=0
a=1
b=3
c=-4
The solution of this quadratic equation will be
x= {-b±√(b²-4ac)}/2a
⇒x= {-3±√(3²-4.1.(-4))}/2.1
⇒x= {-3±√(9+16)}/2
⇒x= {-3±√25}/2
⇒x=(-3±5)/2
⇒x= (-3+5)/2 OR (-3-5)/2
⇒x= 2/2 OR -8/2
⇒x=1 or -4
By checking all the options
Therefore the correct option is Option A: The solution of the quadratic equation is x= -4 and 1

Multiply (a-b) by (2b-a).
Answer:
-2b(a) - a^2 -2b^2
Step-by-step explanation:
Just use the 'foil' method, meaning that you multiply the first number of one part (a), to the first and second to the next part (2b, -a)
Then, multiply the second number of that part (-b), to the first and to the next part (2b, -a)
You would get: -2b(a) - a^2 -2b^2
Multiplication is the process of multiplying. The multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
An expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. The multiplication of the two given expressions (a-b) and (2b-a) can be done as shown below,
(a-b) × (2b-a)
= a(2b-a) -b(2b-a)
= (a × 2b) - (a × a) - (b × 2b) + (b × a)
= 2ab - a² - 2b² + ab
= -a² -2b² + 3ab
= 3ab -a² -2b²
Hence, the multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².

GIVING 30 POINTS PLZ ANSWER
the number a is smaller than the number b by 1/5 of b. by what part of a is b bigger than a?
A is smaller by 1/5 of b
So if you add a and 1/5 of b you would have b:
a + 1/5b = b
Solving for a you have:
A = b - 1/5b = 4/5b
A = 4/5b
Solving for b divide both sides by 4/5:
B = 5/4a
Since 4/4 = 1, this means b I’d bigger than a by 1/4
The answer = 1/4

The population of a coty is 100,000 and the annual growth rate is 4.2%. Write an equation to model the population y after x years
Answer: [tex]1,00,000(1+0.042)^x[/tex]
Step-by-step explanation:
Given
The initial population of a city is [tex]P_o=1,00,000[/tex]
The annual growth rate is [tex]4.2\%[/tex]
after 1 year it is
[tex]\Rightarrow P_1=1,00,000+4.2\%\times 1,00,000\\\Rightarrow P_1=1,00,000(1+0.042)[/tex]
after 2 years, it is

The sum of two numbers is 26. The larger number is 5 more than twice the smaller. What are
the two numbers?
Answer:
Step-by-step explanation:
Let n = the smaller of the two numbers, and since the other number is 5 more than twice the smaller number n, then ...
Let 2n + 5 = the second and larger number.
Since the sum of the two unknown numbers is 26, then we can write the following equation to be solved for n as follows:
n + (2n + 5) = 26
n + 2n + 5 = 26
Collecting like-terms on the left, we get:
3n + 5 = 26
3n + 5 - 5 = 26 - 5
3n + 0 = 21
3n = 21
(3n)/3 = 21/3
(3/3)n = 21/3
(1)n = 7
n = 7
Therefore, ...
2n + 5 = 2(7) + 5
= 14 + 5
= 19
CHECK:
n + (2n + 5) = 26
7 + (19) = 26
7 + 19 = 26
26 = 26
Therefore, the two desired numbers whose sum is 26 are indeed 7 and 19.
Answer:
The answer is 7 and 19

Challenge: Jasmine needs 300 centimeters of fabric to make her new dress. The fabric costs $5 for each meter. How much will her fabric cost to make the dress?
Answer: $15
Step-by-step explanation:
Jasmine needs 300 centimeters
$5 each meter
The first step you need to do is convert 300 centimeters to meters, because it’s $5 for each meter.
(You can use the King Henry Chart to help you)
So, 1 centimeter is 1/100 meter
How much is 300 centimeters in meters?
300x1/100
= 300/100
=3
300 cm= 3m
Now, there is $5 for each meter.
How much does it cost for 3 meters?
= 5x3
= $15
It will cost her $15

Puan Hamidah bought satay from a stall for her children. Her eldest and youngest children ate 1/6 and 0.25 of all the satay respectively. The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay. How many sticks of satay did her eldest child eat?
Answer:
12.01 sticks of satay
Step-by-step explanation:
Let
Total satay bought = x
Eldest child ate = 1/6x
Youngest child ate = 0.25x
Total = 1/6x + 0.25x
= 0.167x + 0.25x
= 0.417x
Remaining satay = x - 0.417x
= 0.583x
The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay.
Her and her other two children = 3 people
Sticks of satay pee person = 14
Total sticks eaten by 3 people = 14 × 3
= 42 sticks
0.583x = 42
x = 42/0.583
= 72.04
x = 72.04 sticks
Total satay bought = x = 72.04 sticks
Eldest child ate = 1/6x
= 1/6 * 72.04
= 12.01 sticks of satay
