Answer: 8th graders should be encouraged to read more. This is because they have the least read pages on average. If you calculate the average number of pages read, the 6th-grade students have a total of 25 pages, the 7th-grade students have a total of 34 and the 8th-grade students have a total of 23. It is because of their lowest total number of pages read that the 8th graders would have the most and should be encouraged to read more.

The degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

What is the measures of the angles in a triangle?

If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry.

A) The sum of the angles in a triangle is 180 degrees. Using this fact, we can write:

m∠d + m∠e + m∠f = (4x-4) + (6x-3) + x = 11x - 7

Since this is the sum of the angles in the triangle, it must equal 180 degrees. Therefore, we can write:

11x - 7 = 180

Solving for x:

11x = 187

x = 17

Therefore, x = 17.

B) Now that we know x, we can find the measure of each angle by substituting it into the expressions given for each angle:

m∠d = 4x - 4 = 4(17) - 4 = 64 degrees

m∠e = 6x - 3 = 6(17) - 3 = 99 degrees

m∠f = x = 17 degrees

Therefore, the degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

The polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

The equation kx^2 - 2x^4 = 0 has the form of a polynomial equation, where k and x are variables. To find the nonzero value of k that will cause the equation to have 2 real solutions, we need to analyze the roots of the equation.

The roots of the equation are the values of x that make the equation equal to zero. To find the roots, we can set each factor of the polynomial equal to zero and solve for x:

kx^2 = 0 and 2x^4 = 0

The first equation gives us x = 0, which is not a valid solution, because it is not a real number.

The second equation gives us x^4 = 0, then x = 0. But x = 0 is not a valid solution for this equation, as it is not a real number.

Therefore, the polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:

List 4.

A sample space is a set that contains all possible outcomes in the context of an experiment.

The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.

Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:

4 x 4 = 16.

This means that the correct list is either the list 3 or the list 4.

As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.

The algebraic expression known as a trinomial contains three terms then the trinomials exists a^2 + b^2 + c^2

What is meant by trinomial?

Three non-zero terms make up a trinomial, which is an algebraic expression. The algebraic expression known as a trinomial contains three terms. An mathematical equation called a trinomial has three terms with on-zero coefficients, each separated by a + or - sign. It is a trinomial if three monomials are divided by addition or subtraction.

When a polynomial has three terms, it is referred to as a trinomial. Its general expression is ax² + bx + c, where a and b are coefficients and c is a constant. In order to factor trinomials, you must follow these three easy steps: Calculate the values of b (middle term) and c. (last term).

A. 8x  

Not a trinomial because, it contains only one term.

B. 3y +5y² + y

The graph of the system of equations y = -2x + 3 and 2x + 4y = 8 is a pair of straight lines passing through the points (2/3, 5/3).

y = -2x + 3 …. (1)

2x + 4y = 8 …. (2)

Substitute eqn (1) in (2)

2x + 4 (-2x + 3) - 8 = 0

Using the multiplicative distributive property, we get

2x - 8x + 12 = 8

By rearranging the above eqn, we get

2x - 8x = 8 - 12

-6x = - 4

Dividing both sides by -2, we get

3x = 2

x = 2/3

Put the value of x in eqn (1)

Step-by-step explanation:

6+4.5 = 10.5 which is greater than 7.5 meaning it cannot create a right angled triangle

A triangle can be formed with the side length of 3.5 cm, 4.5 cm and 7.5 cm.

The one side of the triangle should always measure lower than the sum of remaining two sides of triangle. Based on this concept, let's check the sum and compare it with remaining side to find the possibility of triangle construction.

Side a + side b > side c

3.5 + 4.5 > 7.5

Adding the digits

8 > 7.5

Side b + side c > side a

4.5 + 7.5 > 3.5

Adding the digits

12 > 3.5

side c + side a > side b

3.5 + 7.5 > 4.5

Adding the digits

Based on the estimates above, they sold 3 left-handed and 17 right-handed gloves.

17 right-handed gloves and 3 left-handed gloves were sold.

We must create a set of equations to address this issue.

The total number of gloves sold was 12, and the total income was 940.

Gloves for the right hand (x) = 45.

gloves for the left hand (y) = 50.

Equations x+y=20...

45x + 50y = 561 is the first equation (ii)

Equation derived from equation I x + y = 12 – y (iii)

Equation (ii) becomes 45x + 50y = 940

by substituting equation (iii):

x = 12 - u 45

(12 - y) + 50y = 940;

540 - 45y + 50y = 940;

540 + 7y = 561;

7y = 21 y = 3

Equation I becomes x + y = 20 for y = 3, x + 3 = 20x, and 20- x = 17.

On solving the provided question, we can say that in the triangle If AL = 2, LS = 6,LM =  4, and ST=x+ 2,  as its given, M is the mid point and LM || ST , ST = 4

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.]

Reason:

Subtract 5 from both sides

[tex]\sqrt{\text{x}}+5 = 0\\\\\sqrt{\text{x}}=-5\\\\[/tex]

But recall that the range of the parent square root function is the set of nonnegative values. There's no way to have [tex]\text{y} = \sqrt{\text{x}}[/tex] produce a negative number.

Therefore, the equation [tex]\sqrt{\text{x}}=-5[/tex] has no solutions.

----------------------------

Here's what happens if we squared both sides

[tex]\sqrt{\text{x}}=-5\\\\(\sqrt{\text{x}})^2=(-5)^2\\\\\text{x}=25\\\\[/tex]

That's the potential answer, but we need to verify.

[tex]\sqrt{\text{x}}+5 = 0\\\\\sqrt{25}+5 = 0\\\\5+5 = 0\\\\10 = 0\\\\[/tex]

We get a contradiction, which rules out x = 25 being a possible solution.
