Answer:

a= 7

b= 2

c= -4

Step-by-step explanation:

An expression is defined as a set of numbers, variables, and mathematical operations. The value of a, b, and c is 7, 2, -and 4, respectively.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The sum of the above two expressions can be done as,

[tex]\dfrac{3x}{x+2} + \dfrac{4x}{x-2}\\\\= \dfrac{3x(x+2)+4x(x-2)}{(x+2)(x-2)}\\\\= \dfrac{7x^2+2x}{x^2-4}[/tex]

Comparing the given expression [tex]\dfrac{ax^2+bx}{x^2-c}[/tex] with [tex]\dfrac{7x^2+2x}{x^2-4}[/tex].

Hence, the value of a, b, and c is 7, 2, -and 4, respectively.

Answer:

The son received 2,615.38.

Step-by-step explanation:

In order to know how much the son received, it is best to use algebraic expressions in finding the children's individual shares.

Let x be the son's share and [tex]\frac{3x}{4}[/tex] be the share of each daughter.

The equation will be: 8,500 = x + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex] + [tex]\frac{3x}{4}[/tex]

Next step is: 8,500 =  [tex]\frac{3x+3x+3x+4x}{4}[/tex]

                      8,500 = [tex]\frac{13x}{4}[/tex]

                      8,500 × 4 = 13x

                      34,000 = 13x

                      [tex]\frac{34,000}{13}[/tex] = x

                      x = 2,615.38

The son received 2,615.38

Let's get the share of each daughter:

[tex]\frac{3x}{4}[/tex] = [tex]\frac{(3)(2,615.38)}{4}[/tex] = 1,961.54

Each daughter will receive 1,961.54

Let's check: 2,615.38 + 1,961.54 + 1,961.54 + 1,961.54 = 8,500

Step-by-step explanation:

The value of two integers are -3 and 7.

Here,

Given that;

The product of two integers is -21.

The difference between the integers is -10.

The sum of the two integers is 4.

We have to find the value of two integers.

What is integers?

An integers is a whole number (not a fractional number) that can be positive, negative, or zero.

Now,

Let two numbers are x and y.

Then, The product of two integers is -21.

x * y = -21 ..... (i)

The difference between the integers is -10.

x - y = -10 ..... (ii)

The sum of the two integers is 4.

x + y = 4 .....(iii)

Add equation (ii) and (iii), we get;

x - y + x + y = -10 + 4

2x = -6

x = -3

And,

x + y = 4

-3 + y = 4

y = 7

Hence the two integers x and y are -3 and 7.

The value of z/w is, (8 + 2i)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph is shown in figure.

And, The point z = (6 + 10i)

The point w = (1 + i)

Now,

We can find the value of z/w is,

⇒ z/w = (6 + 10i) / (1 + i)

         = (6 + 10i) (1 - i) / (1 + i) (1 - i)

          = (6 - 6i + 10i - 10i²) / (1 - i²)

          = (6 + 4i + 10) / (1 + 1)

          = (4i + 16) / 2

          = (8 + 2i)

Answer:

Step-by-step explanation:

Total out come is 38

Favorable outcome is 1

Probability is 1/38 ≈ 0.026

The probability of winning if you pick the number 30, and it comes up on the wheel, will be 0.026.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00.

Then the total number of the event will be

Total event = 38 {0, 00, 1, 2, …, 36}

Then the probability of winning if you pick the number 30, and it comes up on the wheel will be

Favorable event = 1 {30}

Then the probability will be

P = 1 / 38

P = 0.026

Answer:

3[|AB|² + |BC|² + |AC|²] = 4[|AD|² + |BE|² + |CF|²]

Step-by-step explanation:

I've attached an image showing a triangle divided into it's medians.

Now, from the attached image, we see that AB, BC & CD are the lengths of sides of triangle while AD, BE & CF are lengths of the 3 medians of the triangle.

Now, to prove our question, we will use appolonius theorem which states that "the sum of the squares of any of the two sides of a triangle is equal to twice the square on half the third side including twice the square on the median that bisects the third side.

Applying this theorem to the image attached, we have the following;

|AB|² + |AC|² = 2[|AD|² + |BC/2|²]

|AB|² + |BC|² = 2[|BE|² + |AC/2|²]

|AC|² + |BC|² = 2[|CF|² + |AB/2|²]

Adding the 3 equations above gives us;

2|AB|² + 2|BC|² + 2|AC|² = 2|AD|² + |BC|²/2 + 2|BE|² + |AC|²/2 + 2|CF|² + |AB|²/2

Collecting like terms;

(2|AB|² - |AB|²/2) + (2|BC|² - |BC|²/2) + (2|AC|² - |AC|²/2) = 2|AD|² + 2|BE|² + 2|CF|²

Thus gives;

(3/2)[|AB|² + |BC|² + |AC|²] = 2[|AD|² + |BE|² + |CF|²]

Multiply both sides by 2 to give;

3[|AB|² + |BC|² + |AC|²] = 4[|AD|² + |BE|² + |CF|²]
