What is an Expression?

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.

Prove that the sum of the squares of the lengths of the medians of a triangle is three fourths the sum of the squares of the lengths of the sides.

Answers

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]

What is an expression?

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)

Stacy wants oil for the cake pops and cupcakes for her birthday party. She needs 1/2 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes. If Stacy has 2 1/2 cups of vegetable oil, how much will she have left over after she makes the cake pops and cupcakes

Answers

Answer:

1 1/4

Step-by-step

The oil left over after she makes the cake pops and cupcakes is 1.25 cups.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Stacy wants oil for the cake pops and cupcakes for her birthday party.

She needs 1/2=0.5 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes.

So, oil required to make cupcakes is 1.5 ×1/2

= 1.5/2

= 0.75

Stacy has [tex]2\frac{1}{2}[/tex] =2.5 cups of vegetable oil

Total vegetable oil used =0.75+0.5

= 1.25 cups

Oil left over is 2.5-1.25=1.25

Therefore, the oil left over after she makes the cake pops and cupcakes is 1.25 cups.

The product of two integers is -21. The difference between the integers is -10. The sum of the two integers is 4. What are the two integers.

Answers

Answer:

-3 and 7

Explanation:

-3 X 7 = 21

-3 – 7 = -10

-3 + 7 = 4

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.

Answers

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.

What is probability?

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

A Woman LEFT 8,500

HER SON AND THREE
DAUGHTER EACH DAUGHTER
SHARE WAS 3/4 OF THE SOn
SHARE
How much DID SON RECIEVED​

Answers

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
