Answer:
(x+6)(x+2) is the factored equation
(-6, -2) is the coordinates
Step-by-step explanation:
find what multiplies to be 12 and adds to be 8
set each factor equal to 0 and solve for x, which is the coordinates
(x+6)(x+2) is the factored equation
(-6, -2) is the coordinates
What is factored equation?The factored equation could be considered as the Quadratic Equation that should be lies in the standard form. The equation in which the factors are computed is known as the factored equation.
Since the equation is
x² + 8x + 12 = 0
So here
the factored equation be (x+6)(x+2) and the coordinates is (-6,-2)

A wall is 15 ft. High and 10 ft. From a house. Find the length of the shortest ladder which will just touch the top of the wall and reach a window 20.5 ft. Above the ground.
Answer:
the length of the shortest ladder is 11.41 feet
Step-by-step explanation:
The computation of the length of the shortest ladder is shown below:
AB^2 = AC^2 + BC^2
AB^2= (10)^2 + (5.5)^2
AB^2= 100 + 30.25
AB^2 = 130.25
AB = 11.41 feet
hence, the length of the shortest ladder is 11.41 feet

Six of the nine students are from Middle Georgia State College. What is the probability that both of the interviewed students are from Middle Georgia State College? Express your answer as a reduced fraction or decimal rounded to at least four decimal places.
Answer: 5/12
Step-by-step explanation:
Six of the nine students are from Middle Georgia State College.
The probability that the first student that's interviewed is from Middle Georgia State College will be 6/9.
Now, when the second student is picked, there'll be 8 students left out of which 5 will be from Middle Georgia State College. Therefore, the probability of choosing someone from there is 5/8.
Now, the probability that both of the interviewed students are from Middle Georgia State College will be:
= 6/9 × 5/8
= 2/3 × 5/8
= 10 / 24
= 5/12

A cylinder had a volume of 100 pi. Find one possible radius and height for the cylinder. Explain how you know your combination is correct.
Answer:
Calculate the volume of a cylinder using the formula V = r2 × π × h. Begin by first finding the area of the circle at one end. Square the radius of the circle and multiply the result by "pi" (the symbol π), or approximately 3.14. Multiply this result by the cylinder's height to get its volume.
Step-by-step explanation:
the height is 4 and the radius is 2
Find the volume of the cone. Use 3.14 for pi. Round your answer to the nearest TENTH. Only write a number for your answer. with work

Is a triangle with sides 4, 6, and 8 a right triangle? Explain your thinking.
Answer:
No it's not
Step-by-step explanation:
In a right triangle the longest side is always the Hypotnuse. With legs a and b and Hypotnuse c, all right triangle follow the Pythagoream Theorem (a^2+b^2=c^2)
If this is a right triangle then it should also follow this rule.
8^2=4^2+6^2
64=16+36
64≠52
So this isn't a right triangle
We can find the solution to the answer by using the Pythagorean Theorem.
a² + b² = c²
4² + 6² = 8²
16 + 36 = 52
8² = 64
52 ≠ 64.
Since 4² + 6² does not equal 8², a triangle with the sides 4, 6, and 8, are not a right triangle.

Answer:
La²+8La+16 = La²+70
Step-by-step explanation:
8La+16 = 70
8La=70-16
La=54/8
La= 6.75
Area b = (6.75+4)*(6.75+4)
Area b = 10.75*10.75
Area b =115.563
The area of a square is the square of its side lengths
The area of square B is 116 centimeter square
Let the side length of square A be (a), and the side length of square B be (b)
So, we have:
[tex]\mathbf{A_a = a^2}[/tex]
[tex]\mathbf{A_b = b^2}[/tex]
From the question, we have:
[tex]\mathbf{A_b = 70 + a^2}[/tex]
[tex]\mathbf{b = 4 + a}[/tex]
Take square of both sides
[tex]\mathbf{b^2 = (4 + a)^2}[/tex]
[tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex]
Substitute [tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex] in [tex]\mathbf{A_b = b^2}[/tex]
[tex]\mathbf{A_b = 16 + 8a+ a^2}[/tex]
So, we have:
[tex]\mathbf{16 + 8a+ a^2 = 70 + a^2}[/tex]
Subtract a^2 from both sides
[tex]\mathbf{16 + 8a = 70}\\[/tex]
Subtract 16 from both sides
[tex]\mathbf{8a = 54}[/tex]
Divide both sides by 8
[tex]\mathbf{a = 6.75}[/tex]
Recall that:
[tex]\mathbf{A_b = 70 + a^2}[/tex]
So, we have:
[tex]\mathbf{A_b = 70 + 6.75^2}[/tex]
[tex]\mathbf{A_b = 115.5625}[/tex]
Approximate
[tex]\mathbf{A_b = 116}[/tex]
Hence, the area of square B is 116 centimeter square

Work out the volume of this prism. Write your answer
a in cm?
120cm
30cm
20 cm
Answer:
24,000 cm³
Step-by-step explanation:
Answer:
V = 48000 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = area of end face × length
The end face is a trapezium with area (A) calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 20 , b₁ = 10 and b₂ = 30 , then
A = [tex]\frac{1}{2}[/tex] × 20 × (10 + 30) = 10 × 40 = 400 cm²
Thus
V = 400 × 120 = 48000 cm³

$3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?
Answer:
Hence, the total amount of money that the investor would have after 6 years will be $ 536.04 .
Step-by-step explanation
Answer:
Interest = $3573.048
Step-by-step explanation:
Given: $3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?
The formula to compound interest is:
I = P(1 + R)^T
First, put in the terms:
I = $3000(1 + 6%)^3
Then calculate:
I = $3000(1 + [tex]\frac{6}{100}[/tex])^3
I = $3000(1 + 0.06)^3
I = $3000(1.06)^3, 1.06^3 = 1.191016
I = $3000 x 1.191016
I = $3573.048

Factor the equation. [tex]x^2+12x+35[/tex]
Answer:
(x + 7)(x + 5)
Step-by-step explanation:
Given
x² + 12x + 35
Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)
The factors are + 7 and + 5 , since
7 × 5 = + 35 and sum = 7 + 5 = + 12, then
x² + 12x + 35 = (x + 7)(x + 5) ← in factored form
