Question 24 of 25 Use the quadratic formula to find the solutions to the equation. x² – 3x+1=0
A. 3: 115 4
B. 3 + 2/5 2
C. 2 + √24 2
D. 5 + 10 3
The solutions to the given quadratic equation are (3+√5)/2 and (3-√5)/2.
What is the quadratic formula?Quadratic formula is the simplest way to find the roots of a quadratic equation.
The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.
The given quadratic equation is x²-3x+1=0.
By comparing x²-3x+1=0 with ax²+bx+c=0, we get a=1, b=-3 and c=1.
Now, x= [3±√((-3)² - 4×1×1)]/2×1
= [3±√(9-4)]/2
= (3±√5)/2
So, the solutions to the given equation are (3+√5)/2 and (3-√5)/2.
Therefore, the solutions to the equation are (3+√5)/2 and (3-√5)/2.

-2x+2y=6 and 7x+4y=23
Let's solve this problem step-by-step:
Let's set:
[tex]-2x + 2y = 6 -- equation 1\\7x+4y=23 -- equation 2[/tex]
(equation1) * 2
[tex]-4x+4y=12--equation3[/tex]
(equation 2) - (equation 3)
[tex]11x = 35\\x= \frac{11}{11}--equation4\\x=1[/tex]
Plug (equation4)'s value of 'x' into (equation1)
[tex]-2(1} )+2y=6\\-2+2y =6 \\2y = 6+2 =8 \\y =4[/tex]
Thus x= 1 and y = 4
Let's check:
[tex]-2(1 )+2(4)=6\\2 +4 =6\\6=6\\ \\7(1)+4(4) )=23\\7+16=23\\ 23 =23\\[/tex]
Answer: x = 1 and y= 4

Answer:
sqrt (2) * sqrt(45) + sqrt (2) * sqrt (80)
45 = 9 *5 "9" is a perfect square so
sqrt (45) = 3 * sqrt (5) * sqrt (2)
sqrt (2) * sqrt (80)
80 = 16 * 5 "16" is a perfect square so
sqrt (2) * sqrt (80) = sqrt (2) * 4 * sqrt(5)
Adding both answers we get
3 * sqrt (5) * sqrt (2) = 3 * sqrt(10)

The ratio of marbles to stones in a large pot is 6 to 7. If there are 42 marbles, then how many stones are there?
Answer:
49 stones
Step-by-step explanation:
Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":
6 m / 7 s = 42 m / X s
cross multiply to get the unknown in the numerator:
6 * X = 42 * 7
divide both sides by 6 to isolate X entirely on the left of the equal sign
X = ( 42 * 7 ) / 6
X = 49
Therefore, there are 49 stones

How to find a side of a square when area is given?
Answer:
length =√area use this formula
The side length of square can be found by taking the square root of Area.
What are Squares?Square are closed polygons which consist of four sides and four angles.
Each angle is 90 degree.
All the sides are of equal length.
So, by the definition of square, we know that the side lengths of square are equal.
The formula to calculate the area of the square is,
Area = a², where a is the length of one side of the square.
Let Area be given, let it be equal to A.
Then,
a² = A
Taking square root on both sides,
a = √A
Hence the side length is found by taking the square root of Area.
