What is the factor of x³ 13x² 32x 20?
The factors are (x + 1)(x + 2)(x + 10)
What is Factorization?The process of breaking down an entity—for instance, a number, a matrix, or a polynomial—into a product of another entity—or factors—that, when multiplied together, yield the original number, matrix, or other entity is referred to as factorization or factoring.
Given Equation x³ + 13x² + 32x + 20
so The value of x³ + 13x² + 32x + 20 is
x³ + x² + 12x² + 12x + 20x + 20
=x² (x+1) + 12x (x+1) + 20(x+1)
=(x + 1)(x² + 12x + 20)
=(x + 1)(x² + 10x + 2x + 20)

Austin went to the store to buy some chicken. The price per pound of the chicken is
$3.50 per pound and he has a coupon for $1.50 off the final amount. With the
coupon, how much would Austin have to pay to buy 3 pounds of chicken? Also, write
an expression for the cost to buy p pounds of chicken, assuming at least one pound is
purchased.
By using multiplication and subtraction, it can be calculated that-
Austin has to pay $9 for 3 pounds of chicken

camilla and megan hung out at the mall on saturday. they spent 1 hour and 25 minutes shopping for clothes and 55 minutes at the food court. then they spent 2 hours and 35 minutes at the video arcade before heading home. if it was 12:55 p.m. when camilla and megan started shopping for clothes, what time was it when they left the mall?
It was 5:50 p.m. when Camilla and Megan left the mall.
Add 1 hour and 25 minutes to 12:55 p.m. to determine the time when Camilla and Megan finished shopping for clothes:
12:55 p.m. + 1 hour and 25 minutes = 2:20 p.m.
Add 55 minutes to 2:20 p.m. to determine the time when Camilla and Megan finished eating at the food court:
2:20 p.m. + 55 minutes = 3:15 p.m.
Add 2 hours and 35 minutes to 3:15 p.m. to determine the time when Camilla and Megan left the mall:

How do you solve and graph inequalities in algebra?
The graph of a two-variable inequality is the set of points that describe all solutions to the inequality.
What are the steps to graphing an inequality?The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.
Step 1: Always begin by separating the variable y from the inequality's left side.
Step 2: Replace the symbol for inequality with that for equality.
Step 3: In the xy plane, graph the boundary line from step 2. You are creating the boundary line that would divide or cut the xy-plane into two sections in this stage.
Step 4: Shading one side or area of the boundary line is the final step.
Step 5: Use this optional step to check or confirm that you have shaded the boundary line's side appropriately.
Here show an example for better understanding:
Let us take a equation, 4x + 8y ≤ -24
Now, solve the above equation in the form of slope-intercept.
4x + 8y ≤ -24
or, 8y ≤ - 4x - 24
or, y ≤ -(1/2)x - 3
This side of the inequality is shaded below (instead of above) because y is lower than (or equal to) the other side.Because working with a "or equal to" inequality, draw a solid line rather than a dashed one. Points on the solid line denote locations where the inequality has been solved.To know more about inequality refer to:

Select the correct answer from each drop-down menu. ∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. the measure of the longest side of ∆abc is units. ∆abc is triangle. if ∆abd is formed with the point d(1, 2) as its third vertex, then ∆abd is triangle. the length of side ad is units.
As per the distance formula, the longest side of triangle ABC is AB and the difference point is 9.1 units.
The formula to calculate the distance of two coordinates is written as
=> d = √(x2 - x1)² + (y2 - y1)²
where (x1, y1) and (x2, y2) are the coordinates.
Here we have given that ∆ABC has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices.
And we need to find the measure of the longest side of ∆ABC is units.
Here we have to take the points A and B and then we need to find the distance for the points AB,
AB = √(-2 - 7)² + (2 - 1)²
AB = √(-9)² + (1)²
AB = √81 + 1
AB = √82 = 9.1
Now, we have to take the next two points, and then we have to find the distance between the points,
BC = √(4 - (-2))² + (2 - 2)²
BC = √(6)² + (0)²
BC = √36 + 0
BC = √36 = 6
Finally, we have to calculate the distance between the point C and A then we get,
CA = √(7 - 4)² + (1 - 2)²
CA = √(3)² + (-1)²
CA = √9 + 1
CA = √10 = 3.2

Discontinuity function is an explanation of development that emphasizes sudden changes or shifts, rather than gradual progressions, in development. This theory suggests that development does not occur in an orderly, linear fashion, but instead involves abrupt changes in which an individual moves from one distinct stage to the next. Examples of discontinuity theory include Piaget’s stages of cognitive development and Erikson’s psychosocial stages, which are made up of distinct stages of development that an individual must progress through before reaching the next stage. According to discontinuity theory, development is not a gradual, continuous process, but rather is made up of distinct stages with abrupt changes in between. This theory has been useful in helping to explain the development of various aspects of an individual, such as cognitive, social, and emotional development.

What is the distance between the points 3 7 and 15 16 on a coordinate plane?
The distance between the points (3 ,7) and (15 ,16) on a coordinate plane is 15 units.
How to calculate distance between two points in coordinate plane?In coordinate geometry, every point is denoted by definite coordinates since every point is situated at a fixed distance from the origin point (0,0). Any two points on a coordinate space are situated at a constant distance since their coordinates are fixed with respect to the origin. A line segment has two endpoints, and the coordinates of the endpoints help to determine the length of the line segment. Let us suppose (x1,y1) and (x2,y2) are the two points on a coordinate space then the distance between these two points is given by the distance formula as per the below:
[tex]d = \sqrt{(x1 - x2)^2 + (y1 -y2)^2}[/tex]
Calculation:given points are (3 ,7) and (15 ,16).
(x1,y1) = (3,7) and (x2,y2) = (15,16)
We know that two points on a plane have a constant distance in between them, and the distance formula gives the distance between these two points.
d =[tex]\sqrt{(x1 - x2)^2 + (y1 - y2)^2}[/tex]
∴ d = √(3 - 15)^2 + (7 - 16)^2
∴ d = 15 unit.

Discontinuity of the Second Type: If a function f(x) at x = a has neither a left-hand limit nor a right-hand limit, it is said to have discontinuity of the second kind.
If the left-hand limit at x tends to point 'a' is equal to the right-hand limit at x tends to point 'a,' but their common value is not equal to f, then the function f(x) has a removable discontinuity at x = a.
