Prove that (4n+1)^2(4n-1)^2 is a multiple of 8 for all integers of n.
thanks.
Answer: i think (4n+1)^2(4n-1)^2 isnt a multiple of 8 for all integers of n because:
(4n + 1)²(4n - 1)²
= [(4n + 1)(4n - 1)]²
= (16n² - 1)²
= 16².n².n² - 2.16.n² + 1
= 8n²(32n² - 4) + 1
can see 8n²(32n² - 4) is a multiple of 8 but 1 isnt a multiple of 8
=> (4n + 1)²(4n - 1)² isnt a multiple of 8 for all integers of n.

Factor the linear expression 15x-10 using the greatest common factor of the terms
Answer:
5(3x-2)
Step-by-step explanation:
Whats the GCF between 15 and 10? There's 1, and 5. We will choose 5 since it's the greatest.
15x - 10
= 5 (3x) - 5 (2)
= 5 (3x-2)

The owner of Animal Lovers Pet Shop just got a delivery of 315 bags of cat food and you need to put the bags on 9 shelves. How many bags will be put on each shelf? Explain the long division steps you used to find your answer.
Answer:
Don't know if you still need help but
If there is 315 bags of cat food you would divide it by the number of shelves so it would be 315 divided by 9 which is 35
Step-by-step explanation: [tex]9\sqrt 315[/tex] (sorry if it looks different) so you would do 9 divided by 31 and since 31 goes into 9 three times you would put a 3 over the 3 in 315 and subtract 27 (since 9 times 3 is 27 and it does not go into 31 equally) from 31 and it will equal 4 so then you bring the 5 down from 315 and put is beside the 4 so then you will have 45 divide by 9 and since 9 goes into 45 five times and it exactly equals 45 you would put the 5 on top beside the 3 above 315. So your answer would be: There will be exactly 45 bags of cat food on each shelf.
I tried to put as much detail as possible sorry its kind of a lot. If its hard to understand here is a picture of what it should look like
Answer:
Sample Response: Divide 9 into 31, multiply 9 and 30 to get 270, subtract 270 from 315 and get 45. Divide 9 into 45, multiply 9 and 5, and get 45, subtract 45 from 45 and get 0. The answer is 35.
Step-by-step explanation:
Divide 9 into 315 and get 35 bags.
Divide 9 into 31, multiply 9 and 30 to get 270, subtract 270 from 315 and get 45. Divide 9 into 45, multiply 9 and 5, and get 45, subtract 45 from 45 and get 0. The answer is 35.
315 divided by 9 is 35, so there will be 35 bags on each shelf.

a new theater is being built for the city ballet. the balcony has 150 seats. the floor has 15 rows with x seats in each row. the number of people in the theater must be under 360 to meet fire safety regulations. what is the solution of thus inequality, and what is its meeting?
answers in the picture
The solution is Option A.
15x + 150 < 360 . The new theater must have fewer than 14 seats in each row on the floor to meet fire safety regulations
The inequality equation is x < 14
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Let the total number of people in the theater be = 360 people
The number of seats in the balcony = 150
Let the number of seats be x
The number of rows = 15
The number of seats in 15 rows = 15x
So , the inequality equation is
Number of seats in 15 rows + number of seats in the balcony < total number of people in the theater
Substituting the values in the equation , we get
15x + 150 < 360
On simplifying the equation , we get
Subtracting 150 on both sides of the equation , we get
15x < 210
Divide by 15 on both sides of the equation , we get
x < 14
Therefore , the value of x is less than 14
Hence , the new theater must have less than 14 seats in each row

Question 20
The price of a cup of coffee was $2.65 yesterday. Today, the price fell to
$2.50. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
5.6% decrease
Step-by-step explanation:
Answer:
5.7% decrease
Step-by-step explanation:
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!
solve the equation by factoring x^3+17x= -72

Consider a computer that uses 6 bits to represent integers: 1 bit for the sign and 5 bits for the actual number. What's the largest positive integer it can represent?
Answer:
31
Step-by-step explanation:
Therefore, range of 5 bit unsigned binary number is from 0 to (25-1) which is equal from minimum value 0 (i.e., 00000) to maximum value 31 (i.e., 11111).
The largest positive integer will be 31.
It is given that a computer has uses 6 bits to represent integers out of which 1 bit is for sign and 5 bits is the actual number.
We have to find out the largest positive integer it can represent.
What do you mean by the binary number system ?
In the Binary number system there are only two numerals , represented by 0 and 1, and its digits are often referred to as bits.
As per the question ;
A computer has uses 6 bits to represent integers.
∵
Max number = [tex]2^{n}[/tex]
and the largest possible number we could represent using n no. of bits = [tex]2^{n}[/tex] - 1
Here if ;
n = 6 bits
So ,
Max number = [tex]2^{6}[/tex] = 64
and
The largest number = [tex]2^{6}[/tex] - 1
= 64 - 1
= 63
It is also given that ;
Out of 6 bits , 1 bit is for sign and 5 bits is the actual number ;
So ;
for n = 5 bits
The largest positive integer will be ;
= [tex]2^{5}[/tex] - 1
= 31
Thus , the largest positive integer will be 31.
