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]

A gym employee is paid monthly. After working for three months, he had earned $4,500. To determine how much money he will make over a six-month period'he created the table below
1. if he continues to earn at the same rate how much will he have working 5 months?
2. After how many months will the gym employee have made $19,500?
3. write an equation to represent the constant of proportionality
Answer:
$9000
Step-by-step explanation:
A gym employee has earned in 3 months =$4500
Then his monthly salary =$4500/3 =$1500
After six months he will earn = 6 × his monthly salary
= 6×$1500=$9000

The area of a rectangular parking lot is 4947 m2.
If the length of the parking lot is 97 m, what is its width?
Width of the parking lot:
The perimeter of a rectangular pool is 304 m.
If the width of the pool is 68 m, what is its length?
Length of the pool:
Answer:
1. width = 51 m
2. length = 84 m
Step-by-step explanation:
So remember, the area is (length * width).
It is given that the length is 97, and the area is 4947.
So plug this into a formula:
length * width = area
97 * width = 4947
Solve using inverse operations;
97 * width = 4947
/97 /97
width = 51m
The perimeter of a rectangle can be found by doing, (2 * (length + width)).
The width is given, it is 68m. The perimeter is also given, 304m. So just form an equation using this information:
2 * ( length + width) = perimeter
2 * (length + 68 ) = 304
Distribute;
2 * ( length + 68) = 304
2 length + 136 = 304
Inverse operations;
2length + 136 = 304
-136 -136
2length = 168
/2 /2
length = 84m
Answer:
The answer for number 1 is width = 51 m
The answer for number 2 is length = 84 m

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
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.

Step-by-step explanation:
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.
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]

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.
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.

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
