Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66
x ≈ 18.12, 1.88

What is the equation of the line that passes through the point (6, 8) and has a slope 1/2
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.

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

Which of the following is the best approximation of the volume of the cylinder below?
Answer:
B
Step-by-step explanation:
[tex]v = \pi {r}^{2} h \\ = 8 \\ v = \pi {8}^{2} \times 3 = 3.14 \times 64 \times 3 = 602.88 = 602.9[/tex]
The volume of the cylinder is 2411.5 cm³ in the given figure. which is the correct answer would be an option (A).
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
As per the given figure,
The radius of a cylinder is 16 cm and the height of the cylinder is 3 cm.
The volume of a cylinder = πr²h
The volume of a cylinder = π(16)² × 3
The volume of a cylinder = 3.14(256) × 3
The volume of a cylinder = 2411.5 cm³
Thus, the volume of the cylinder is 2411.5 cm³ in the given figure.

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.
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

Step-by-step explanation:
FG = EH ( being opposite sides of parallelogram)
3z + 8 = 5z - 14
5z - 3z = 8 + 14
2z = 22
z = 11

If the perimeter of a square is 120f+80 inches, what is the length, in inches, of each side of the square?
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.
