[tex]\frac{1}{(m-4)(m-3)}[/tex]

Answer:

The expression which equivalent is 1/[(m - 4)(m - 3)] ⇒ 2nd answer

Step-by-step explanation:

* Lets revise how to divide two fractions

- To divide a/b and c/d change the division operation to multiplication

  operation and reciprocal the fraction after the division sign

# a/b ÷ c/d = a/b × d/c

* Lets solve the problem

∵ (m + 3)/(m² - 16) ÷ (m² - 9)/(m + 4)

- Use the factorization to simplify the fractions

∵ m² - 16 is a different of two squares

- The factorization of the different of two squares a² - b² is

∵ a² = a × a , -b² = b × -b

∴ a² - b² = (a + b)(a - b)

- Use this way with m² - 16

∵ m² = m × m

∵ -16 = 4 × -4

∴ m² - 16 = (m + 4)(m - 4)

- Similar factorize m² - 9

∵ m² = m × m

∵ -9 = 3 × -3

∴ m² - 9 = (m + 3)(m - 3)

- Now lets write the fraction and simplify it

∵ (m + 3)/(m² - 16) ÷ (m² - 9)/(m + 4)

∴ (m + 3)/[(m + 4)(m - 4)] ÷ [(m + 3)(m - 3)]/(m + 4)

- Change the division operation to multiplication operation and

  reciprocal the fraction after the division sign

∴ (m + 3)/[(m + 4)(m - 4)] × (m + 4)/[(m + 3)(m - 3)]

- We can cancel (m + 4) in the denominator of the first fraction with

 (m + 4) in the numerator of the second fraction and cancel (m + 3)

 in the numerator of the first fraction with (m + 3) in the denominator

 of the second fraction

∴ 1/(m - 4) × 1/(m - 3) ⇒ multiply the two fractions

∴ 1/[(m - 4)(m - 3)]

* The expression which equivalent is 1/[(m - 4)(m - 3)]

Answer:

y=-12

Step-by-step explanation:

For the slope of line given two points I like to line up and subtract. Then put 2nd diff/1st diff.

Let's do that:

(-6  , -12 )

(0 ,  -12)

-----------

-6      0

2nd/1st=0/-6=0  slope should have been obvious as 0 since there is no rise in the points (you can see this from their y-coordinate)

Anyways the y-intercept is when it crosses the y-axis. The y-axis is crossed when the x-coordinate is 0. You have that given here which is -12.

So the equation is y=0x-12 or jusy y=-12

If you already knew that horizontal lines were of the form y=a number

then you could have just skip to y=-12

y=-12 just means all the ordered pairs on this line have the y-coordinate being -12 which is what we have in the set of points you gave

The exact value of sin(11π/12) is (√6 - √2)/4.

To find the exact value of sin(11π/12), we can use trigonometric identities to determine the value of an equivalent angle in the first quadrant. Since π/12 is the reference angle of 11π/12, which is in the second quadrant, we can find the sine of the equivalent angle in the first quadrant. The reference angle in the first quadrant is π/12. Therefore, the exact value of sin(11π/12) is the same as the exact value of the sine of π/12. Using a trigonometric identity, we find that sin(π/12) = (√6 - √2)/4.

Answer:

The area of DBE = 27 square units

Step-by-step explanation:

Area of ABC = 3 square units

In the figure, we can see that ABC was enlarged so that BDE is formed where side BD = 6 and AB was = 2

Hence ABC was enlarged 3 times its size.

We know by formula that:

Area of ABC = 1/2(base x perpendicular)

3 = 1/2(2 x p)

=> p = 3

As ABC was enlarged 3 times its size, the perpendicular of BDE must be 3*p

= 3*3 = 9

AREA OF DBE = 1/2(base*perp)

= 1/2(6*9)

= 27 square units

Answer:

(x + 5 y)^2

Step-by-step explanation:

Simplify the following:

4 (x - y)^2 - 12 (x - y) (x + y) + 9 (x + y)^2

(x - y) (x - y) = (x) (x) + (x) (-y) + (-y) (x) + (-y) (-y) = x^2 - x y - x y + y^2 = x^2 - 2 x y + y^2:

4 x^2 - 2 x y + y^2 - 12 (x - y) (x + y) + 9 (x + y)^2

4 (x^2 - 2 x y + y^2) = 4 x^2 - 8 x y + 4 y^2:

4 x^2 - 8 x y + 4 y^2 - 12 (x - y) (x + y) + 9 (x + y)^2

(x + y) (x - y) = (x) (x) + (x) (-y) + (y) (x) + (y) (-y) = x^2 - x y + x y - y^2 = x^2 - y^2:

4 x^2 - 8 x y + 4 y^2 - 12 x^2 - y^2 + 9 (x + y)^2

-12 (x^2 - y^2) = 12 y^2 - 12 x^2:

4 x^2 - 8 x y + 4 y^2 + 12 y^2 - 12 x^2 + 9 (x + y)^2

(x + y) (x + y) = (x) (x) + (x) (y) + (y) (x) + (y) (y) = x^2 + x y + x y + y^2 = x^2 + 2 x y + y^2:

4 x^2 - 8 x y + 4 y^2 - 12 x^2 + 12 y^2 + 9 x^2 + 2 x y + y^2

Grouping like terms, 4 x^2 - 8 x y + 4 y^2 - 12 x^2 + 12 y^2 + 9 (x^2 + 2 x y + y^2) = 9 (x^2 + 2 x y + y^2) + (4 y^2 + 12 y^2) - 8 x y + (4 x^2 - 12 x^2):

9 (x^2 + 2 x y + y^2) + (4 y^2 + 12 y^2) - 8 x y + (4 x^2 - 12 x^2)

4 y^2 + 12 y^2 = 16 y^2:

9 (x^2 + 2 x y + y^2) + 16 y^2 - 8 x y + (4 x^2 - 12 x^2)

4 x^2 - 12 x^2 = -8 x^2:

9 (x^2 + 2 x y + y^2) + 16 y^2 - 8 x y + -8 x^2

9 (x^2 + 2 x y + y^2) = 9 x^2 + 18 x y + 9 y^2:

9 x^2 + 18 x y + 9 y^2 + 16 y^2 - 8 x y - 8 x^2

Grouping like terms, 9 x^2 + 18 x y + 9 y^2 + 16 y^2 - 8 x y - 8 x^2 = (9 y^2 + 16 y^2) + (18 x y - 8 x y) + (9 x^2 - 8 x^2):

(9 y^2 + 16 y^2) + (18 x y - 8 x y) + (9 x^2 - 8 x^2)

9 y^2 + 16 y^2 = 25 y^2:

25 y^2 + (18 x y - 8 x y) + (9 x^2 - 8 x^2)

x y 18 + x y (-8) = 10 x y:

25 y^2 + 10 x y + (9 x^2 - 8 x^2)

9 x^2 - 8 x^2 = x^2:

25 y^2 + 10 x y + x^2

The factors of 25 that sum to 10 are 5 and 5. So, 25 y^2 + 10 x y + x^2 = (x + 5 y) (x + 5 y):

(x + 5 y) (x + 5 y)

(x + 5 y) (x + 5 y) = (x + 5 y)^2:

Then, we move all variables to the left side, and all constants to the right side

[tex]-8x+3x>5-4\\-5x>1[/tex]

Now, we divide the inequality by -5, which changes the sign orientation

[tex]\frac{-5x}{-5} <\frac{1}{-5}\\ x<-\frac{1}{5}[/tex]

Answer:

The answer to this question is D- 15.

Step-by-step explanation:

This is how to solve it

30 students and 2 at random this are the key words

you do 30/2

your answer is equal to 15

Answer: B. 435

Step-by-step explanation: This is a combination problem. The teacher is going to choose two students at random, but the order in which the two students are chosen doesn't matter. (meaning, student A being chosen 1st and student B being chosen 2nd is the same result as Student B being chosen 1st and student A being chosen 2nd) Since this is a combination's problem, we use the combination function nCr.

The nCr function is written as [tex]\frac{n!}{r!(n-r)!}[/tex], where n represents the total number of things to choose from while r represents the number of objects  that will be taken from the set. In this case, n=30 since there are 30 total students to choose from while r=2 since the teacher is picking two students from the group of 30.  The exclamation marks next to the variables represent a factorial.

A factorial is the product of all positive integers less than or equal to the integer next to the factorial. For example, 6! indicates 6 factorial, which is equal to 6 x 5 x 4 x 3 x 2 x 1 = 720. Therefore, 30! equals 30 x 29 x 28 x 27 x 26......... and so on until its been multiplied by every positive integer less than 30.

Using the nCr function, we plug the values in to get [tex]\frac{30!}{2!(30-2)!}[/tex]. After doing some simplification and factoring, we get the equation [tex]\frac{30 * 29}{2}[/tex], which yields 435 possible combinations. This can be done because 30 factorial and 28 factorial share 28 factors due to the nature of factorials, simplifying 30 factorial to simply 30 multiplied by 29. The equation yields 435 possible combinations, thus meaning that there are 435 possible ways to choose 2 students from 30 students.

The formula is given by:

[tex]d = \sqrt{(x_{2} -x_{1} )^{2}+(y_{2}- y_{1} )^{2} }[/tex]

Here,

[tex](x_{1},y_{1}) = (4,6)\\ (x_{2},y_{2}) = (7,-3)\\Putting\ the\ values\\d = \sqrt{(7-4)^{2}+(-3-6)^{2}}[/tex]

Hence, the following expression will give the distance between given points

[tex]d = \sqrt{(7-4)^{2}+(-3-6)^{2}}[/tex]

Solving it will give:

[tex]d = \sqrt{(3)^{2}+(-9)^{2}}\\= \sqrt{9+81}\\=\sqrt{90}[/tex]
