Answer:
5(x-3)(x-3)
Step-by-step explanation:
First we can divide everything by 5:
[tex]\frac{5x^{2} -30x+45}{5} = x^{2} -6x+9[/tex]
Now we find 2 numbers that multiply to give +9 and add to give -6:
This would be -3 and -3. Now we substitute these numbers inside of -6 by splitting -6x into -3x and -3x:
[tex]x^{2} -3x-3x+9[/tex]
Now we factor the first 2 terms:
[tex]x(x-3)[/tex]
Now we factor the last 2 terms:
[tex]-3(x-3)[/tex]
Now we only copy one bracket and the things outside the bracket we put them into 1:
(x-3)(x-3)
Now we multiply everything by 5 :
5(x-3)(x-3)
Answer:
5(x-3)( x-3)
Step-by-step explanation:
First we notice that all the factors are divisible by 5 because the ending of the coefficients is 0 or 5
5 (x² -6x+9)
5 ( x -3) ² , because x² -6x+9 = 9x-3)²
5 (x-3)( x-3)

In the morning, the temperature is "-5'F." The temperature increases by 13'F, then decrease by 5'F. Write an equation to represent the situation.
The equation to represent the temperatures are A = ( -5F ) + ( 13F ) - ( 5F )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the initial temperature in the morning be a = -5F
Now , the increase in temperature is b = 13F
And , the decrease in temperature is c = -5F
On simplifying the equation , we get
A = a + b + c
A = ( -5F ) + ( 13F ) - ( 5F )
Therefore , the value of A is ( -5F ) + ( 13F ) - ( 5F ) = 3F
Hence , the equation is A = ( -5F ) + ( 13F ) - ( 5F )

Basketball tickets were $5 for floor seats
$2 for the grandstand seats
I’d 210 people attended and paid $660, how many people bought floor seats?
130 people's bought floor seats ...
Explanation:→ First , we need to identify and define the unknown terms.
F: # of floor seats sold
G: # of grandstand seats sold
• F + G = 210 {210 is the total number of seats sold}
• 5F + 2G = 660 {the 5 , 2 and 660 refer to amounts of dollars} .
→ We now have two equations in two unknowns , which we should be able to solve.
→ Let's solve the first equation for G, and then substitute the value of G into the second equation , so that we have will have a single equation with only F as the unknown ...;
→ F represents the number for which we are looking: The number of floor seats sold.
Let's find numbers of people's bought floor seat:F + G = 210
F - F + G = 210 - F
G = 210 - P
→ 2F+ 5G = 660
→ 2F + 5(210 - F) = 660
→ 2F + 1050 - 5F = 660
→ - 3F + 1050 = 660
→ - 3F + 1050 - 1050 = 660 - 1050
→ - 3F = - 390
→ F = - 390 / - 3 = 130
→ F = 130
• Hence , 130 people's bought floor seats ...

A true or false test has 5 questions. what is the probability of guessing the correct answers to all the questions?
Answer:

Step-by-step explanation:
There are only two options: right or wrong.

Since there are 5 questions, and 5 right answers are desired: [tex]\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}[/tex]

Answer:
A. 29
B. 22
C. 36
Step-by-step explanation:
To find the median, you have to put the numbers in order from least to greatest which would be 18, 19, 22, 28, 28, 30, 32, 36, 37, 42. Then you find the number in the middle, and there are 10 numbers. So, you split them in half and 18, 19, 22, 28, 28 would be on one half, and 30, 32, 36, 37, 42 would be on the second half. The middle of 28 and 30 is 29, so that is your median.
To find the lower quartile, you have to divide the numbers into two sides with the lowest numbers on one side and the highest numbers on the other. Since there are 10 numbers, there will be 5 on each side. On the lowest number side there will be 18, 19, 22, 28, 28. To find the lower quartile, you find the middle number of the 5 numbers. 22 is in the middle, so that is the lower quartile.
To find the upper quartile, you have to take the highest numbers which are 30, 32, 36, 37, 42. Then you find the middle number, just like finding the lower quartile. The number in the middle is 36, so that is the upper quartile.

Sarah’s mom took 3 hours to clean, but when Sarah helped, it took them 2 hours to clean. How many hours will it take Sarah to clean herself?
Answer:
It takes them 1.875 hours.
Step-by-step explanation:
Here, the job is cleaning the house.
Mom does 1 job in 3 hours.
In 1 hour, mom does 1/3 of the job.
Dad does 1 job in 5 hours.
In 1 hour, dad does 1/5 of the job.
Mom and dad working together do the job in x hours.
In 1 hour, mom and dad together do 1/x of the job.
1/3 + 1/5 = 1/x
5/15 + 3/15 = 1/x
8/15 = 1/x
8x = 15
x = 15/8 = 1.875
