2-(x+1)/(x-2)-(x-4)/(x+2)can be written as a single fraction in the form (ax+b)/(x^(2)-4) where a and b are intergers
Answer:
a = 3, b = -18
Step-by-step explanation:
You can start by getting a common denominator in the fractions [tex]\frac{x+1}{x-2}[/tex] and [tex]\frac{x-4}{x+2}[/tex]. You can multiply the first one by [tex]\frac{x+2}{x+2}[/tex] to get [tex]\frac{(x+2)(x+1)}{x^2-4}[/tex]and you can multiply the second by [tex]\frac{x-2}{x-2}[/tex] to get [tex]\frac{(x-4)(x-2)}{x^2-4}[/tex]. You can simplify the fractions:
[tex]\frac{(x+2)(x+1)}{x^2-4}[/tex] - [tex]\frac{x^2+3x+2}{x^4-4}[/tex]
[tex]\frac{(x-4)(x-2)}{x^2-4}[/tex] - [tex]\frac{x^2-6x+8}{x^2-4}[/tex]
Now we can rewrite the equation:
[tex]2-\frac{x^2+3x+2}{x^2-4} -\frac{x^2-6x+8}{x^2-4}[/tex]
and combine the terms with the same denominator:
[tex]2+\frac{-x^2-3x-2-x^2+6x-8}{x^2-4}[/tex]
[tex]2+\frac{-2x^2+3x-10}{x^2-4}[/tex]
Now, to add the two into the fraction, we multiply it by [tex]x^2-4[/tex] to get [tex]2x^2 - 8[/tex].
[tex]\frac{2x^2-8-2x^2+3x-10}{x^2-4}[/tex]
And simplify:
[tex]\frac{3x-18}{x^2-4}[/tex]
a = 3, b = -18
The value of the integers a and b are 3 and - 18 respectively.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
Firstly , let's find out a common denominator in the fractions , [tex]\frac{x+1}{x-2}[/tex] and [tex]\frac{x-4}{x+2}[/tex] .
The first one can be written as :
= [tex]\frac{x+1}{x-2}[/tex] × [tex]\frac{x+2}{x+2}[/tex]
= [tex]\frac{(x+1)(x+2)}{x^{2} - 4}[/tex]
and the second one can be written as :
= [tex]\frac{x-4}{x+2}[/tex] × [tex]\frac{x-2}{x-2}[/tex]
= [tex]\frac{(x-4)(x-2)}{x^{2} - 4}[/tex]
The expression will be :
= 2 - [tex]\frac{x+1}{x-2}[/tex] - [tex]\frac{x-4}{x+2}[/tex]
= 2 - [tex]\frac{(x+1)(x+2)}{x^{2} - 4}[/tex] - [tex]\frac{(x-4)(x-2)}{x^{2} - 4}[/tex]
= [ 2 (x²- 4) - (x+1) (x+2) - (x-4) (x-2)]/ [(x²- 4)]
= [2x² - 8 - x² - 3x - 2 - x² + 6x - 8] / [(x²- 4)]
By simplifying it , we get :
= [tex]\frac{3x-18}{x^{2} - 4}[/tex]
If we compare it with the given form which is [tex]\frac{ax + b}{x^{2} -4}[/tex] we get :
[tex]\frac{3x-18}{x^{2} - 4}[/tex] = [tex]\frac{ax + b}{x^{2} -4}[/tex]
or
3x - 18 = ax + b
or
The values of a and b are :
a = 3 and b = -18.
Therefore , the value of the integers a and b are 3 and - 18 respectively.

-6 ( x – 8) = 60
Show steps
Answer:
-6(x-8)=60x-8= -10x= -10+8x= -2hope it helps...
Answer:
-2
Step-by-step explanation:
-6 ( x - 8) = 60
• divide -6 on both sides
-6 and -6 cancel out and 60 ÷ -6 = -10
• your new equation is now x - 8 = -10
• add 8 to both sides x - 8 = -10
+8. +8
• x = -2
What is the Surface Area Formula for a Square Pyramid? I need the formula
Answer:
The surface area of a square pyramid is the sum of the areas of all its 4 triangular side faces with the base area of the square pyramid. If a, h, and l are the base length, the height of the pyramid, and slant height respectively, then the surface area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

can anyone please help me I'm timed
Answer:
Triangles ABC and ADC are congruent because they all have the same angles. AC bisects angle A which means that both triangles have the same angle measurement. C is a 180 degree angle and is bisected, meaning that both angles created are 90 degree angles and thus the same degree measurement.
Another reason why they are congruent is because the sides are equal. AB and AD are the same length because the picture shows a singular line on both sides meaning they are the same. The height of both triangles are the same because they share a height. BC and CD are the same length because AC is bisecting BD, meaning both sides are equal in length. Thus, both triangles have the same side measurements.
Answer:
yes it's all correct good luck

Oceanside Bike Rental Shop charges 18 dollars plus 8 dollars an hour for renting a bike. Alyssa paid 50 dollars to rent a bike. How many hours did she pay to have the bike checked out ?
Answer:
4 hours
Step-by-step explanation:
Cost of renting a bike at Oceanside Bike Rental Shop = 18 + 8x
Where,
x = number of hours for renting the bike
Alyssa paid 50 dollars to rent a bike.
How many hours did she pay to have the bike checked out ?
C = 18 + 8x
50 = 18 + 8x
Subtract 18 from both sides
50 - 18 = 18 + 8x - 18
32 = 8x
Divide both sides by 8
32 / 8 = 8x / 8
4 = x
x = 4 hours
