Answer:
[tex] x = \dfrac{ 3\pm \sqrt7}{2} [/tex]
Step-by-step explanation:
The given equation to us ,
[tex]\implies 6x = 2x^2 + 1 [/tex]
So we will use quadratic formula and solve out for x .
[tex]\implies 6x = 2x^2 + 1 \\\\\implies 2x^2 -6x + 1 = 0 \\\\\implies x = \dfrac{-b\pm \sqrt{ b^2-4ac}}{2a} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ (-6)^2-4(2)(1) }}{2(2)} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ 36 - 8 }}{4} \\\\\implies x = \dfrac{ 6 \pm \sqrt{ 28}}{4} \\\\\implies \boxed{\boxed{ x = \dfrac{ 3\pm \sqrt7}{2} }}[/tex]
I NEED HELP PLS!! it shouldnt be too hard bc im in 6th grade
Answer:
2x + 1
Step-by-step explanation:
That person added everything together that was shown which is incorrect. You shouldn't add the 12x + 3 as that should be the end result. You add 3x + 3x + 4x + 2 to get 10x + 2. You then subtract that by 12x +3 which is 2x + 1

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
A = x(x − 4) − (8)(x − 4) − 4(8)
A = x(x − 4) + (8)(x − 4) + 4(8)
A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
Step-by-step explanation:
here .................
Answer:
A. A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Step-by-step explanation:
Total area:
A(t) = x(x - 4)Area of the stage:
A(s) = 0.5(8)(x - 4)Area of the closet:
A(c) = 4(8)Area to be painted:
A = A(t) - A(s) - A(c)A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Correct choice is A

The diameter of a circle is 12 cm. Find its circumference in terms of pi
Answer:
37.68
Step-by-step explanation:
to get radius divide diameter by 2.
formula for circumference is 2×r×pi.
since we already have the diameter we don't need to ÷ by 2 to get the radius because then we would have to multiply it back again.
pi=3.14.
12×3.14=37.68.

8 more than twice a number is 18.
Answer:
18 + (18 more than) 2x (twice a number) = (is) 8
18+2x=8
2x=-10 (subtract 18 from both sides)
x=-5 (divide both sides by 2)

Factor the following :
Answer:
(6x - 7y)(6x + 7y)
Step-by-step explanation:
36x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
36x² - 49y²
= (6x)² - (7y)²
= (6x - 7y)(6x + 7y)
Answer:
(6x + 7y)(6x - 7y)
Step-by-step explanation:
36x² - 49y²
= (6x)² - (7y)²
= (6x + 7y)(6x - 7y)
In this question we used the identity-
a² - b² = (a + b)(a - b)

A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group who say that the most fun way to flirt is in person. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.
I have attached the complete question.
Answer:
Mean; μ = 1.648
Standard deviation;σ = 0.8610
Step-by-step explanation:
From the image attached, we can see that the probabilities given under the p(x) column are;
0.091
0.334
0.408
0.166
Let's find out if these values give a probability distribution.
ΣP(x) = 0.091 + 0.334 + 0.408 + 0.166
ΣP(x) ≈ 1
Their sum is approximately 1 and they are all between 0 and 1. Thus, it is a probability distribution.
Mean is found by;
μ = ΣxP(x)
From the table attached, x = 0, 1, 2, 3
Thus;
μ = (0 × 0.091) + (1 × 0.334) + (2 × 0.408) + (3 × 0.166)
μ = 1.648
Standard deviation is given by;
σ = √[Σ(x - μ)²•P(x)]
σ = √[((0 - 1.648)² × 0.091) + ((1 - 1.648)² × 0.334) + (2 - 1.648)² × 0.408) + ((3 - 1.648)² × 0.166)]
σ = 0.8610

Question 7: Find the value of x. The numbers below are in degrees.
140
S
50
20
Given:
A figure.
To find:
The value of x.
Solution:
Draw two parallel lines as shown in the below figure.
If a transversal line intersect two parallel lines, then alternate interior angles are same.
[tex]a=20[/tex] (Alternate interior angle)
[tex]d=b[/tex] (Alternate interior angle) ...(i)
The value of angle d is
[tex]d=50-a[/tex]
[tex]d=50-20[/tex]
[tex]d=30[/tex]
Using (i), we get
[tex]b=30[/tex]
If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.
[tex]c+140=180[/tex]
[tex]c=180-140[/tex]
[tex]c=40[/tex]
Now,
[tex]x=b+c[/tex]
[tex]x=30+40[/tex]
[tex]x=70[/tex]
Therefore, the value of x is 70.
The mathematical expression 2 ∈ V means:
It could be nonsense without any more context…
But more likely than not, V is understood to be some set of numbers, in which case the statement "2 ∈ V" means "2 belongs to the set V".
