Which of the following represents the set of possible rational roots for the
polynomial shown below?
x2 + 5x2 – 3x – 20 = 0

Answer: £27.96

Step-by-step explanation:

Since the bookshop has an offer. "Buy one book and get one free!" and we are told that Ria gets 8 books from the shop with that offer. This simply means that Ria bought 4 books and also got 4 free.

Since the normal price of each book is £6.99 and Ria bought 4 books, the amount Ria spend will be:

=£6.99 × 4

= £27.96

Answer:

[tex]5^{3}[/tex]

=5*5*5

=125

Answer:

In order to write this in scientific notation, we must move the decimal from the beginning all the way to between the 5 and the 9

Note: you can move the decimal anywhere you want but typically scientific notation will have the decimal in between the first and second digit.

Since we move the decimal 24 digits to the right, our answer will be

5.972 * 10^24

or

5.972E24

Answer:

Let x be the smallest integer (the first integer)

1st: x, 2nd: x + 1, 3rd: x + 2, 4th: x + 3, 5th: x + 4

Hence,

x +  x + 1 + x + 2 + x + 3 + x + 4 = 10

5x + 10 = 10

5x = 0

x = 0

Therefore, the answers are

0, 1, 2, 3, 4

Step-by-step explanation:

Integers include all positive integers, negative integers and 0.

0 is an integer but it is neither positive nor negative.

Answer:

[tex]\boxed{x_1 = \frac{2}{3} ~~or~~x_2 = 1}[/tex]

.

Step-by-step explanation:

[tex](3x - 2)(5x - 4) = (3x - 2)^2[/tex]

[tex]15x^2 - 12x - 10x + 8 = 9x^2 - 12x + 4[/tex]

[tex]15x^2 - 22x + 8 - 9x^2 + 12x - 4 = 0[/tex]

[tex]6x^2 - 10x + 4 = 0[/tex] → divide both segment by 2

[tex]3x^2 - 5x + 2 = 0[/tex]

[tex](3x - 2)(x - 1) = 0[/tex]

[tex]3x - 2 = 0[/tex]

[tex]3x = 2[/tex]

[tex]x = \frac{2}{3}[/tex]

Answer:

The largest is 25.

Step-by-step explanation:

If the first integer is x, the second is x+1 and the third is x+2.

When you multiply the largest by 4: (x+2)*4

It is 31 more than 3 times the smallest: (x+2)*4 = (x)*3+31

When you simplify you get : 4x+8 = 3x+31

Which means: x = 23

But since you want the largest you get: 23+2 = 25

The greatest of the three consecutive odd integers will be  [tex]19[/tex].

Integers are whole numbers that can be positive, negative and zero.

We have,

Let first integer [tex]= x[/tex]

Second integer [tex]= x+2[/tex]

Third integer  [tex]= x+4[/tex]

Now,

According to the question,

[tex]4(x+4) = 3(x)+31[/tex]

Simplifying;

[tex]4x+16=3x+31[/tex]

Taking [tex]x[/tex] variable on one side and constant on the other;

[tex]4x-3x=31-16[/tex]

[tex]x=15[/tex]

So,

Now substitute the value of [tex]x[/tex]  in every integer's equation,

i.e.

First integer [tex]= 15[/tex]

Second integer [tex]= 17[/tex]

Third integer  [tex]= 19[/tex]

So, the greatest of the three consecutive odd integers is [tex]19[/tex].

Hence, we can say that the greatest of the three consecutive odd integers will be  [tex]19[/tex].

Answer:

Please check explanations for answer

Step-by-step explanation:

Let us choose 4 and 6

When we talk of the greatest common factor, we mean the highest number that is a factor of both numbers

The factors of 4 are 1,2,2 and 4

Factors of 6 are 1,2,3 and 6

So as we can see the only common factors to both are 1,2 but the highest here is 2

The least common multiple refers to the smallest number which divides 4 and 6 at the same time without leaving a remainder

Multiples of 4 are 4,8,12 , 16,20 •••••

multiples of 6 are 6,12,18,24

As we can see, the lowest common number to both is 12

Answer:

$11.43/ft squared

Step-by-step explanation:

160/14 is $11.428 which is rounded to $11.43

HOPE THIS HELPS!

Answer:

The unit rate is $11.43/ft because if you take 14 divided by 14 to get 1 foot you have to take 160 divided by 14 to get how much it costs for 1 ft. So the answer is $11.43.

Answer:

100 students.

Step-by-step explanation:

First because it says "..2 out of 3" you have 2 boxes (i'm using a tape diagram) for the students that prefer gel toothpaste and 1 box for the others/don't prefer gel toothpaste students. Since there are 150 students in the school in total you will divide the number of students (150) by the 3 boxes and get 50. Each box will be filled with 50. Students that prefer gel toothpaste : 50 x 2 = 100 (students) Students that don't prefer gel toothpaste : 50 x 1 = 50 (students).

The answer is below

Step-by-step explanation:

The question is not complete. But I would show you how to solve the problem.

Two events A and B are said to be independent if the occurrence of event A does not affect the occurrence of event B and vice versa. P(A and B) = P(A) * P(B).

Two events A and B are said to be mutually exclusive if event A and event B cannot occur at the same time. P(A and B) = 0.

Two events A and B are said to be complementary when event A occurs if and only if event B does not occur and vice versa.

Answer:

21

Step-by-step explanation:

49.10 - 5= 44.10

44.10 divided by 2.10= 21

Answer:

I suppose that you want to find the region of solutions.

We start with the inequality:

3х - 4y ≤ -20

To solve this, will be easier to write this as a linear relationship, we can do this as follows:

3x - 4y ≤ -20

-4y ≤ -20 - 3x

y ≥ (-20 - 3x)/-4

(Notice that the "direction" of the sign changes, this is because we divided both sides by a negative number).

y ≥ 5 + (3/4)*x

Now we have the equation of a line, and we know that y will be equal or greater than the line, this means that we need to draw the line and shade all the area above the line, as shown in the graph below:
