The product of (x+y)(x²+xy+y²) gives x³ + 2x²y + 2xy² + y³.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

(x+y)(x²+xy+y²)

Multiplying the terms

= x(x²+xy+y²)) + y(x²+xy+y²)

= x³ + x²y + xy² + yx² + xy² + y³

= x³ + 2x²y + 2xy² + y³

Hence, the expression gives x³ + 2x²y + 2xy² + y³.

Mean is calculated to get an idea of the average of the observations in the data set.

The average value of the observations in a data set is called the mean or average . It is calculated by dividing the sum of observations by the number of observations i.e.

u = (x1 + x2 + x3 + .... + xn)/n

where u is the mean , x1 , x2 ...,  xn are data observations and n is the number of observations.

For example, we have values as 1,2,3,4,5 and we want to calculate the mean . Then it is calculated by

u = (1+2+3+4+5) / 5 = 3.

So, the mean is 3.

A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to discover factors. A number or other mathematical object is factorized or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. One factorization of the polynomial x2 - 4 is 3 5, which is also a factorization of the number 15.

The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.

If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.

Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:

4x - 3y = -12

-3y = -4x - 12

-3y/-3 = -4x/-3 - 12/-3

y = 4/3x + 4

This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.

The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

In mathematics, there are numerous ways to use the word "order." It most frequently refers to the quantity of elements in (for example, conjugacy class order, graph order, group order, etc.) or describes the biggest term (for example, curve order, surface order, or polynomial order) that appears in a mathematical object.

Here,

=>Rate of evaporation=k=dr/dt

=> amount still present=R.

Thus ,It's a first order reaction.

So, half life=0.693/k.

20=0.693/k.

=> k=0.0346

Now,

60% of active ingredient has been evaporated.

So, 40% left.

Time taken=T=(2.303/k)log(R/0.4R)

T=(2.303/0.0346)log(5/2)

On solving the provided question, we can say that - If you put all the numbers together by digits, the total must be a multiple of three. so answer is 17

The divisibility rule is a concise and practical approach to check, often by looking at the integer's digits, whether a given integer is divisible by a given set divisor without actually executing division. Without actually doing the division procedure, you may quickly discover if a given number can be divided by a defined divisor using the divisibility test. When dividing two numbers exactly, the quotient must be an integer and the remainder must be zero.

Answer:

All three angles must add up to 180 degrees

Step-by-step explanation:

The slope of the linear equation y = -3x + 4 is -3, and the y-intercept is 4.

To calculate the slope of a linear equation, the formula is m = (y2 - y1) / (x2 - x1). The slope is calculated by selecting two points on the line, (x1, y1) and (x2, y2), and then subtracting the first point's y-value from the second's and dividing the result by the first point's x-value minus the second's. For the equation y = -3x + 4, the y-intercept is 4, which is the b-value in the equation y = mx + b. The y-intercept is the point where the line crosses the y-axis. To calculate the y-intercept, set x = 0 and solve for y. For the equation y = -3x + 4, when x = 0, y = 4. Therefore, the y-intercept is 4.

Therefore , we can calculate the side of the length of the square by finding the square root of the given area.

Here,

The base length times the height of any quadrilateral yields the area of that shape.

Since the shape is square, we can be certain that all of its sides are equal in length.

Using this information, we can work backwards to determine the length of one side by taking the square root of the area.

For example : Square having area of 25

We can find its length by taking square root of 25

Which comes out to be √25 = 5

Thus , 5 is a length of the side of the square.

Answer:

Here is the answer

Step-by-step explanation:

To find the perimeter of a triangle, we need to add up the lengths of all three sides. In this case, the sides of the triangle are given by the expressions 3x2 - y2, 4x2 - 7xy + 4y, and -3x + 7xy + 8y2.

To find the perimeter, we can simply add up these three expressions:

Perimeter = 3x2 - y2 + 4x2 - 7xy + 4y - 3x + 7xy + 8y2

= 7x2 - 3xy + 12y

This is the perimeter of the triangle. Note that the perimeter is a scalar quantity, not a vector, so it does not have a direction associated with it.

The graph of the equation x = -4 is shown in the image attached below.

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis) respectively.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).

By critically observing the graph (see attachment), we can reasonably infer and logically deduce that the x-intercept is equal to -4.
