The solution to the quadratic equation is x = -6 ± 2√7
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² + 12x + 25 = 17
Subtracting 17 on both sides , we get
x² + 12x + 8 = 0
And , roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
On simplifying , we get
x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2
x = -6 ± √ ( 144 - 32 ) / 2
x = -6 ± √112/2
And , the value of x = -6 ± 2√28/2
x = -6 ± 2√7
Hence , the solutions are x = -6 + 2√7 and -6 - 2√7

Answer:
y = 3/8, x = 7/4
Step-by-step explanation:
x = 2y+1
-7(2y+1) - 2y = -13
-14y - 7 - 2y = -13
-16y - 7 = -13
-16y = -6
y = 3/8

If the perimeter of a square is 120f+80 inches, what is the length, in inches, of each side of the square?
Answers
Answer:
30f + 20
Step-by-step explanation:
A square has four sides, all of equal length. If we call that side length x, then the perimeter - the total length around the square - is 4x. To find the side length given the perimeter then, we can simply divide the perimeter by 4.
Our perimeter here is 120f + 80, and dividing each term by 4 gives us a side length of 30f + 20.

What is the area of triangle AOB? *picture attached* show work also please
Answers
Answer:
The area of the traingle AOB is 30 (Rounded up result)
Step-by-step explanation:
7.8 cm and 10 cm.
10/2= 5 cm
Then Reversed Pitagora's Formula:
Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84
Then Square root of 35, 84 is 5,98.
5.98 is the height of the triangle AOB
With the height we can calculate the area
We use the formula (B*H)/2
So is (10*5,98)/2, that makes 29,9
Just round up to 30 and that's the area.

What is the equation of the line that passes through the point (6, 8) and has a slope 1/2
Answers
Answer:
y=1/2x+5
Step-by-step explanation:
Plug it into the formula for a point and a slope.
(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))
Y-8=1/2(x-6)
Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.
Solve the equation for m:
2m +4
———— = W

A. m = 4w - 2
B. m = 4w - 8
C. m = 2w - 4
D. m = 8w-4
Answers
Answer:
2m +4 =8w
2m = 8w -4
m=8w-4 / 2
m= 4w - 2

You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.
Answers
Answer:
90
Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted
The number of units the 10% sales decline represents is 90
what is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900
= 900 -( 10/100 )×900
= 900 - 90
= 810
Hence, the number of units the 10% sales decline represents is 900-810 =90

Which calculation and answer show how to convert 3/12 to a decimal
Plz help ASAP
Answers
Answer:
Its C
Step-by-step explanation:
It is C becuase when converting a fraction to a decimal, you just divide the numerator by the denominator
Basically solve the fraction
3/12=1/4
1/4 is a bencmark so right away you should know that should equal to 0.25 since its a quarter.
Or you can always look it like this
3 is the numerator
the “/“ between is basically ”divided by”
And the 12 is the denominator
Now read the equation in that order
3/12= 3 DIVIDED BY 12
