Answer:
To simplify any rational expressions, we apply the following steps:
Factorize both the denominator and numerator of the rational expression. Remember to write each expression in standard form.
Reduce the expression by cancelling out common factors in the numerator and denominator
Rewrite the remaining factors in the numerator and denominator.
Step-by-step explanation:
Example:
Simplify: (x^{2} + 5x + 4) (x + 5)/(x^{2} – 1)
Solution:
Factoring the numerator and denominator to get;
⟹ (x + 1) (x + 4) (x + 5)/(x + 1) (x – 1)
Now cancel the common terms.
⟹ (x + 4) (x + 5)/(x – 1)
Explain why three angle measures do not determine a unique triangle. How many triangles are determined by three angles measures?
You can either form no triangles or an endless number of triangles when you are given three angles.
For Example -
How many distinct triangles can you construct using angles of 30, 60, and 90 degrees?
Use a protractor to create one of the angles needed to form a triangle. You can adjust the side lengths to your desired length. Make another angle at the end of one of the sides, then link the sides together. You've constructed a triangle.
You should note that you chose the side lengths. This implies that you might choose differently. This allowed you to create an infinite number of distinct triangles using the same angles.
Hence, we can form infinite number of triangles when only the measurements of three angles is given

Mary's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs mary $5.35 per pound, and type b coffee costs $4.15 per pound. this month, mary made 181 pounds of the blend, for a total cost of $853.15. how many pounds of type b coffee did she use?
Mary used 96 pounds of type b coffee this month.
Using algebraic expression and equation, we can solve how much of each type of coffee did Mary used that month.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that that month, Mary made 181 pounds of the blend that is a mixture of two types of coffee, we can express this as:
181 = a + b
where a = pounds of type a coffee that costs $5.35 per pound
b = pounds of type b coffee that costs $4.15 per pound
Also, the total cost of the blend that month is $853.15, which is the sum of the total cost of the two types of coffee. We can express that as:
$853.15 = $5.35(a) + $4.15(b)
Using substitution method to solve the two equations,
181 = a + b ⇒ a = 181 - b
$853.15 = $5.35(181 - b) + $4.15(b)
853.15 = 968.35 - 5.35b + 4.15b
5.35b - 4.15b = 968.35 - 853.15
1.2b = 115.2
b = 96
a = 181 - b
a = 181 - 96
a = 85
Hence, Mary used 85 pounds of type a coffee and 96 pounds of type b coffee that month.

a=6, b=9, m
Two sides without an angle measurement, such as a = 6 m and b = 9 m, can be used to create an infinite number of acute triangles.
How many distinct acute triangles can we make, for instance, if our side lengths are 6 m and 9 m and our angle value ranges from 0 to 90 degrees?
Create a triangle with a 45-degree angle, sides that are 10 and 10 meters long, and a third side that can be stretched to the required length. You've constructed a triangle.
We can create a whole different Acute triangle that is identical to this one by altering the length and angle of the third side.
Never overlook picking the side angles and lengths. It's possible that you'll choose to proceed in a different way. There are an infinite amount of distinct triangles that can be created with the same angles.
As a result, we can make an infinite number of acute triangles using a single angle and a single side length.

Step-by-step explanation:
Hello, and thank you for asking your question on Brainly!
This problem is basically telling is to isolate the variable g. But how are we to do so, when it's being sandwiched inside a variety of numbers and letters? The problem looks harder than it seems. But do not fret!
When you're in a trail in the woods and you get lost, the most logical thing is to do the opposite of where you just went in order to try and reach home. We can use this same analogy for math. We just try and use the opposite operation for every action that the function is being acted on!
Let be the original equation,
[tex]u=\sqrt{Ng+Q^3 }[/tex]
Looks pretty complicated right? We want to isolate the variable g, so let's get rid of this 'roof' over their heads.
To get rid of the square root, we can square both sides by two; this negates the square root, and opens up the right section of the equation.
[tex]u=\sqrt{Ng+Q^3 }[/tex]
[tex]u^2 =(\sqrt{Ng+Q^3 })^2[/tex]
[tex]u^2=Ng+Q^3[/tex]
Now, we have to make sure we get the variable g alone. Let's subtract Q cubed to the other side, we can subtract it over to get rid of it on the right hand side.
[tex]u^2=Ng+Q^3\\-Q^3 ~~~~~ -Q^3[/tex]
[tex]u^2-Q^3=Ng[/tex]
We're almost close! Now, all we have to do to isolate the variable g is to divide the whole equation by N, so the right hand side it cancels out. This is the opposite of N multiplied by g.
[tex]\frac{u^2-Q^3}{N} =g[/tex]
It wasn't so bad now, was it? I hope this helped! g is now isolated and this is the end of the problem.

A work survey found that 8 out of every 10 employees went on vacation last summer. If 3 employees' names are randomly chosen, with replacement, what is the probability that all 3 employees went on vacation last summer?
These are independent events because the likelihood of the first event has no bearing on the probability of the second event. Let V represent choosing holidaymakers from the previous summer.
What is probability ?
Probabilities are mathematical explanations of the likelihood that an event will occur or that a proposition is true.
P(V)= (8/10)*(8/10)*(8/10)
P(V)= 512/1000
= 51.2%.
The likelihood of an event is represented by a number between 0 and 1, with 0 typically signifying impossibility and 1 typically signifying certainty.
Basic probability is governed by three primary rules: the addition rule, the multiplication rule, and the complement rule.

Find the slope of the line that passes through the two points. (4,5) and (1,8)
The slope between the two given points (4,5) as well as (1,8) is -1.
What exactly is the slope of a line?A line's slope is a measure of its steepness & direction.
The slope of a line is defined as a change in y coordinate in relation to a change in x coordinate.
The net change in y coordinates is Δy, while the net change in x coordinates is Δx.As a result, the y coordinate change in relation to the x coordinate change could be composed as,m = Δy/Δx
where,m is the slope
Slope is also written as tan θ = Δy/Δx. Where, tanθ is also called as the line's slope.Now, as per the stated question;
The slope of a line can be calculated using only two points on a straight line. With the coordinates of two points, we can employ the slope of line formula.
Let the coordinates of those 2 points from where the line is passing is;
P1 = (x₁, y₁)
P2 = (x₂, y₂)
The slope of the line is estimated as;
Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)
The values of the coordinates are given as;
(x₁, y₁) = (4,5) and,
(x₂, y₂) = (1,8)
Substitute the given values of coordinates in the formula to get the slope;
m = (8 - 5)/(1 - 4)
m = 3/(-3)
m = -1
Therefore, given the coordinates of such two points, the slope of a line passing through them is found to be -1.

P=3q + 500 is a linear equation where p is the price of the cellular plan and q is the amount of data used in the form of GB
In order to form a linear equation that describes the amount of data you can use in terms of the amount of money that you are willing to spend, we just need to shuffle the linear equation in order to get the coefficient if q as 1
First step, we need to move 500 from right hand side to left hand side which would change the sign from + to -.
