The total number of books Lori owns is 45.

Let x be the total number of books.

Mark owns 1/4 of x

Kevin own 1/3 of x

Kevin owns 9 more than Mark, so;

1/4x - 1/3x = 9

Multiplying both sides by 12

4x - 3x = 108

x = 108

The total number of books is 108

but;

Mark owns 1/4 of x = 1/4 x 108

Mark = 27

while Kevin owns 1/3 x 108

Kevin = 36

Therefore, Lori would own

108 - 36 - 27 = 45

Lori's number of books will be 45.

The value of 3 √ 4 √ x is 48

A number's square root is a value that, when multiplied by itself, yields the original number. The other way to square an integer is to find its square root. Squares and square roots are hence related concepts.

Assuming that x is the square root of y, the equation would be written as x=y or as x2 = y. The radical symbol for the number's root is "" in this instance. The square of the positive number is represented by multiplying it by itself. The original number is obtained by taking the square root of the square of a positive number.

As per the question, 3 √ 4 √ x when x =4096

first we need to calculate square root of 4096 by  prime factorisation method

4096 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

4096 = (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2)

√4096 = √((2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2))

√4096 = 2 × 2 × 2 × 2 × 2 × 2

√4096 = 64

Therefore the square root of 4096 = 64.

x=64

now putting the value of x in  3 √ 4 √ x

= 3 √ 4 √ 64

= 3 √  256

=3×16

=48

so the value of 3 √ 4 √ x  is 48

The figure's circumference, as seen in the diagram, is 60.84 m.

What are some instances of perimeters?

The perimeter of an object is the space surrounding it. For instance, your house has a fenced-in yard. The perimeter is the length of the fence. If the yard is 50 feet by 50 feet, your fence is 200 feet long.

The formula below is used to determine the figure's perimeter.

Formula:

Equation 1: P = 2L + W + W / Equation 1:

P = The figure's perimeter

L is the figure's length.

W is the figure's width.

Considering the query,

Given:

L = 15 m\sW = 12 m\sπ = 3.14

Replace the values in equation 1 with these ones.

P = (15×2)+12+(12×3.14/2)

P = 30+12+18.84

P = 60.84 m

As a result, the figure's perimeter is 60.84 meters.

The expression 2x² + 7x + 3 can be factored as (2x + 3)(x + 1).So, the factored form of 2x² + 7x + 3 is (2x + 3)(x + 1).

To factor this expression, we can use the method of grouping. First, we rewrite the expression as:

2x² + 7x + 3

Then, we group the first and last terms and the middle term:

(2x² + 3) + (7x)

Next, we try to factor in the first group. Since 2x² + 3 can be rewritten as (2x + 1)(x + 3), we can factor the entire expression as:

(2x + 1)(x + 3) + (7x)

Finally, we can rearrange the terms to get the factored form:

(2x + 7x) + (1)(3)

This simplifies to:

(2x + 7x)(1) + (3)

Which is equal to:

(2x + 7x + 3)

And finally:

(2x + 7x + 3) = (2x + 3)(x + 1)

So, the factored form of 2x² + 7x + 3 is (2x + 3)(x + 1).

Answer:

m = -3

Step-by-step explanation:

The slope is rise/run or (y2 - y1) / (x2 - x1)

We see the y increase by 30 and the x decrease by 10, so the slope is

-30/10 = -3

So, m = -3

Answer:

Slope = -3

Step-by-step explanation:

Formula of slope,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now the slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (11 -(-19))/(-12 -(-2))

→ m = (11 + 19)/(-12 + 2)

→ m = 30/-10

→ m = -(30/10)

→ [ m = -3 ]

Hence, the slope is -3.

Similarly, if you wanted to say that the value of x is much greater than the value of y, you could write "x ≫ y."

The symbols "≪" and "≫" are used in mathematics to express a strong inequality between two values. They are similar to the familiar inequality symbols ">" (greater than) and "<" (less than), but they indicate a greater degree of inequality.

For example, if you wanted to say that the value of x is much less than the value of y, you could write "x ≪ y." This means that x is much smaller than y, and the difference between the two values is significant.
