The product of √6 and √12 is option b 6√2.
Given,
Two square roots : √6 and √12
We have to find the product of these square roots:
That is,
√6 × √12
Multiplying square roots:
Multiply the two numbers as usual without considering the square root.After multiplying consider the square root of the product.It will be the product of the square roots.So here,
Multiply the numbers,
√6 × √12 = 6 × 12 = 72
Now consider the square root of 72
√72 = √36 × √2 = 6√2
That is, the product of the square roots √6 and √12 is 6√2

I’m not really sure what to do
For the function f(x) = -(x + 1)² + 4, identify the vertex, domain, and range.
Answer:
Vertex: (-1, 4)
Domain: All Real Numbers
Range: y < or equal to 4
Step-by-step explanation:
Vertex: Using my calculator, i determined the vertex. The vertex is the most bottom/top point of the parabola, depending on if it opens down or up.
Domain: All the answers have all real numbers so its obvious.
Range: the parabola opens down at (-1, 4), so all the numbers on the y axis below 4 fit in with the line
In a class of 36 students for every four students who could only speak one language, five students could speak more than one language. How many students in the class can speak more than one language?
7 students in the class can speak more than one language.
Given that,
Total student = 36
For every four students who could only speak one language
For every five students who could only speak one language.
To determine how many students in the class can speak more than one language.
Since,
For every five students who could only speak one language,
= 36 / 5
quotient = 7 ; remainder = 1
Implies that, 7 students in the class can speak more than one language.
Thus, 7 students in the class can speak more than one language.

Find a polynomial function of least degree having only real coefficients, a leading coefficient of 1, and zeros of 2 and 3+ i
The polynomial function of least degree with only real coefficients is y = x³ - 8 · x² + 22 · x - 20.
What is the polynomial function of least degree with real coefficients?
The statement indicates that the polynomial has a leading coefficient of 1 and zeros of 2 and 3 + i. By algebra of quadratic equations, equations with real coefficients with complex roots are α + i β and α - i β. Then, all the roots of the polynomial function of least degree are 2, 3 + i and 3 - i. The complete expression is shown below:
y = 1 · (x - 2) · (x - 3 - i) · (x - 3 + i)
y = (x - 2) · [x² - 3 · x - i · x - 3 · x + i · x + (3 + i) · (3 - i)]
y = (x - 2) · (x² - 6 · x + 9 - i²)
y = (x - 2) · (x² - 6 · x + 10)
y = x³ - 6 · x² + 10 · x - 2 · x² + 12 · x - 20
y = x³ - 8 · x² + 22 · x - 20

Step-by-step explanation:
A food manufacturer donates money to schools based on the number of
its product labels the school collects. The students at one school collected
2,100 product labels in three months. The number of labels collected in the
first two months was three times the number of labels collected in the thirc
month. How many product labels were collected in the third month?
The total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.
Let the number of labels collected in the first two months be 3 x.
We are given that the number of labels collected in the first two months was three times the number of labels collected in the third month.
So, the number of labels collected in the third month = 3 x / 3 = x
Now, we are also given that:
The total number of labels collected by the students at the school = 2100.
So, we get the equation as:
3 x + x = 2100
4 x = 2100
x = 2100 / 4
x = 525 labels.
Therefore, we get that, the total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.

Using a proportional relationship, it is found that:
1 lemon is required for 2 cups.6 cups are required for 3 lemons.The graph for this relationship is given at the end of the answer.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For this problem, we have that the variables are:
x: number of lemons.y: number of cups.Hence the proportional relationship between these two variables is given by:
y = 2x.
Then:
1 lemon is required for 2 cups. (y = 2, then x = 1).6 cups are required for 3 lemons. (x = 3, then y = 6).The linear graph of the relationship, considering the given points, is given at the end of the answer.

In the second array, we have 4 patterned circles and 1 plain circle.
In the third array, we have 1 patterned circle and 4 plain circles.
In the fourth array, we have only 1 plain circle.
So, total patterned circles = 5 + 1

What’s the answer to 4x(x+3) < -24
The answer to the inequality is expressed as x< 1 and x< -4
What are inequalities?Inequalities are mathematical expressions having both sides unequal or rather not equivalent to each other.
Given the inequality;
4x (x+3) < -24
First, expand the bracket
4x² + 12x < - 24
Let's turn to quadratic inequality
4x² + 12x - 24 < 0
Factorize further
4 ( x² + 3x - 4) < 0
4 ( x² + 4x - x - 4) < 0
4 ( x(x + 4) - 1 (x + 4) ) < 0
4(x - 1) ( x + 4) < 0
expand the bracket
4x - 4 < 0
x < 1
And
4x + 16 < 0
x < -4
Thus, the answer to the inequality is expressed as x< 1 and x< -4

What is the solution for item 1?The situation is modeled by the following linear function:
P(n) = 2.75 + 4.25n.
We have that P(n) = 24, hence we have to solve for n.
24 = 2.75 + 4.25n.
n = (24 - 2.75)/4.25
n = 5.

2(3w - 4) = 220
3w - 4 = 110
3w = 114
w = 114/3

The length of the rectangle is of 72 inches.
What is the solution for item 7?The situation is modeled by the following equation:
P(x) = 125 + 50x.
We have that P(x) = 425, hence we solve for x as follows:
425 = 125 + 50x
50x = 300
x = 300/50
x = 6.
He rented the limousine for 6 hours.

Work out an expression for the nth term
Please please answers this question ill give u like and mark as brainlist
Answer:
2n² + n
Step-by-step explanation:
Given sequence:
3, 10, 21, 36, ...
Work out the first differences between terms:
[tex]3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36[/tex]
As the first differences are not the same, work out the second differences.
[tex]7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15[/tex]
As the second differences are the same, the sequence is quadratic and will contain an n² term.
The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.
To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:
[tex]\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}[/tex]
Therefore, we need to add n to 2n² to match the sequence.
Therefore, the nth term of this sequence is 2n² + n.

The measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°
Complement of an AngleFrom the question, we are to determine the complement of the given angle measure
From the given information, the measure of angle K (m ∠K) is (6x + 12)°
NOTE: If two angles are complementary, the measures of the angles sum up to 90°
Let the complement of angle K be angle L.
Thus,
∠K + ∠L = 90°
(6x + 12)° + ∠L = 90°
6x° + 12° + ∠L = 90°
∠L = 90° - 12° - 6x°
∠L = 78° - 6x°
∠L = (78 - 6x)°
