The expression that is equivalent to x³ - 25x is x(x² - 25) and x(x + 5)(x - 5)

An equation is an expression that shows the relationship between two or more numbers and variables

Given the expression:

x³ - 25x

Factoring the equation gives:

x(x² - 25)

= x(x + 5)(x - 5)

The expression that is equivalent to x³ - 25x is x(x² - 25) and x(x + 5)(x - 5)

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.

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.

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

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

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.
