Step-by-step explanation:
Write the following expression in its
simplest form.
2x²y
xy
-
3x + 12x.xy
To write the expression in its simplest form, we need to simplify each term and then combine like terms.
The first term of the expression is 2x²y. This term is already in its simplest form and doesn't require any further simplification.
The second term of the expression is xy. This term is also in its simplest form and doesn't require any further simplification.
The third term of the expression is -3x. This term is also in its simplest form and doesn't require any further simplification.
The fourth term of the expression is 12x.xy. To simplify this term, we need to distribute the 12 over the x and y. So, we get 12x.y.
Now that all terms are simplified, we can combine like terms. Since the terms xy and 12x.y are the same, we can add them together to get (12+1)xy = 13xy.
So, the expression in its simplest form is 2x²y + 13xy - 3x.
We can further simplify the above expression by combining x²y and xy together as (x²+1)xy = x³y
So, the final expression in its simplest form is x³y + 13xy - 3x.

After kicking, one coach likes to play practice games with 6 players on each
team. She doesn’t like any team to have more or fewer than 6 players and
she doesn’t like anyone to be left off a team. What are the possible numbers
of players who must show up to practice so that the coach can make these
teams?
Note that the question is about numbers in multiples of 6 or which can be divided equally by 6. Thus the likely number of people who must show up to practice so that the coach can make these teams are 6, 12, 18, 24, 30, 36, 48, and so on. The bottom line is that the number must be a common multiple of 6.
What is the proof that each of the numbers above will create teams of x players each?One way to show that each of the numbers above will equal an exact team of 6 without anyone left off is by dividing each by 6. If we get an integer, then we are correct. Thus:
6/6 = 1 Team12/6 = 2 Teams18/6 = 3 Teams24/6 = 4 Teams30/6 = 5 Teams36/6 = 6 teams48/6 = 8 Teams.Hence, the above Common Multiples are correct.

So on solving the provided question, we can say that - in the circle angle DGF = 59 .
What is circle?Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

What is a line graph?A line graph, also known as a line chart or a line plot, is commonly drawn to show information that changes over time. You can plot it by using several points linked by straight lines. It comprises two axes called the “x-axis” and the “y-axis”. The horizontal axis is called the x-axis.In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G.Line graphs are used to track changes over short and long periods of time For the second triangle, the rise is 1 and the slope is 2. This gives us a slope of 1/2.Any linear function will have the same slope throughout the entire line.me. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one groupThe slope is 1/2 throughout the entire line.Looking at the first triangle, the rise is 2 and the run is 4.

We can restricted domain of the quadratic(y=x^2 +4) is {-∞,0} or {0,∞}.
What is Quadratic Equation?
Having the form ax^2 + bx + c = 0, quadratic equations are second-degree algebraic expressions. From the term "quad," which meaning square, comes the word "quadratic." A quadratic equation is a "equation of degree 2," to put it another way. A quadratic equation is employed in numerous situations. In addition, there are many uses for quadratic equations in physics, engineering, astronomy, etc.
There are a maximum of two solutions for x in the second-degree quadratic equations. These two solutions for x are denoted as (, ) and are also known as the roots of the quadratic equations.
What is Domain?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
It cannot have an inverse function because the largest exponent is even (2), unless the domain is constrained.
We know that the vertex is at x = 0 since our equation is already in vertex form;
a(x - h)^2 + k, or 1(x - 0) + 4
In order to limit the domain to only one side of x = 0

The equation that she can use as statement 5 is c) (3x + 24): 51 = 3x: 85.
To prove that x = 12, Dora must first prove that the segments ST and RQ are parallel. This can be done by showing that the angles formed by their intersection are congruent.
Since the angles, QRT and STP are congruent (statement 2) and the angles SPT and QPR are congruent (statement 3), the Triangle-Angle Angle Similarity Postulate can be applied to show that triangle SPT is congruent to triangle QPR (statement 4).
Now, the corresponding sides of the two triangles must be in proportion in order to prove that x = 12. For this, Dora can use the equation (3x + 24) : 51 = 3x : 85 (statement 5). This equation states that the ratio of the lengths of the corresponding sides of the two triangles is equal to the ratio of 3x to 51 and 3x to 85, respectively.
Since the ratio of the sides of the two triangles must be equal, then 3x + 24 must be equal to 85 and 3x must be equal to 51. Solving for x, we get x = 12, proving that if segment ST is parallel to segment RQ, then x = 12.

Is there a factor on this pls help Questiob : 5x ^ 2 - 8x + 9
Answer:
(5x - 3)(x - 3)
Step-by-step explanation:
Yes, the expression "5x^2 - 8x + 9" can be factored.
One way to factor it is to find the two numbers that multiply to give 9 (the constant term) and add to give -8 (the coefficient of x). These two numbers are 3 and -3.
We can use these two numbers to factor out the common factor (x - 3) from the expression:
5x^2 - 8x + 9 = (5x^2 - 8x) + 9
= (5x^2 - 8x + 9) - 9 + 9
= (5x^2 - 8x + 9) - (3x - 3x)
= (5x - 3)(x - 3)
So the fully factored form of the expression is (5x - 3)(x - 3)
So, (5x - 3) and (x - 3) are the factors of the expression "5x^2 - 8x + 9"

On solving the provided question, we can say that by using the triangle, ∠LNM=35° and ∠NML=55°
What is triangle?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.
∠LNM=(4x+3)°
∠NML=(5x+15)°
∠NLM=90°
Since, its right angle triangle, sum of all angle is 180°
∠LNM+∠NML+∠NLM=180°
(4x+3)+(5x+15)+90=180°
9x+18=90°
9x=72
