The equation which shows one way to determine the factors of x3 4x2 5x 20 by grouping is x²(x + 4) + 5(x + 4).
How to find factor of polynomial?The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.
The polynomial equation given in the problem is,
[tex]x^3 +4x^2 +5x+ 20[/tex]
Take out the greatest common factor from the first two term which is x^2 and from the last two terms which is 5 as,
[tex]x^2(x +4)+5(x+ 4)\\[/tex]
Simplify it further,
[tex](x+4)(x^2+5)[/tex]

Find the distance between the two points. (3,4) ✓ [?] (-2,-1) Enter the number that goes beneath the radical symbol.
The distance between the points (3,4) and (-2,-1) is found being 5√2 units.
What is the distance between two points ( p,q) and (x,y)?The shortest distance(length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

If the radius of a circle is 2 inches, what is the area of the circle? Use 3.14 for pi
Answer:
12.56 in squared
Step-by-step explanation:
the formula for area is radius x radius x pi
So you do 2x2x3.14
(I would just do 4x3.14)
And then you get 12.56
The box-and-whisker plot below shows the age distribution of people at a family reunion. a box-and-whisker plot is shown. the number line goes from 8 to 72 in increments of 8. the whiskers range from 8 to 71, and the box ranges from 23 to 47. a line divides the box at 38. the stem-and-leaf plot below shows the same data. a stem and leaf plot is shown. the stems from top to bottom are 0, 1, 2, 3, 4, 5, 6, 7. the first column of leaves is 8, 0, 3, 1, 0, 0, 0. the second column of leaves is 9, 1, 3, 6, 1, 2, 1. the third column of leaves is blank, 4, 5, 6, 2, 3, blank. the fourth column of leaves is blank, 5, 6, 8, 4, 6, blank. the fifth column of leaves is blank, blank, 6, 9, 6, blank, blank. the sixth column of leaves is blank, blank, blank, 9, blank, blank, blank. the seventh column of leaves is blank, blank, blank, 9, blank, blank, blank. which of the following best explains why one graph appears skewed and one graph appears symmetrical? the scale of the box-and-whisker plot does not start at zero. the interval of the box-and-whisker plot is too large. the interval of the stem-and-leaf plot is not consistent. the scale of the stem-and-leaf plot is too small for the set of data.
One graph appears skewed, and one graph appears symmetrical because the interval 2 stem and leaf plots is not consistent, statement third is correct.
What is a histogram?It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.
The number line goes from 8 to 72 in incremental of 8, such as:
8, 16, 24, 32, 40, 48, 56, 64, 72
The whiskers range is from 8 to 71 and
Box ranges from 23 to 47.
The line divides the box at 38.
The mid-point of the line plot is at 40 and at first inspection, the stem and leaf plot appears to be accurate. In the stems, however, 5 is omitted entirely, giving the pattern a symmetrical rather than skewed appearance.
Thus, one graph appears skewed, and one graph appears symmetrical because the interval 2 stem and leaf plots is not consistent, statement third is correct.

Brianna was offered a job that paid a salary of $77,000 in its first year. The salary
was set to increase by 2% per year every year. If Brianna worked at the job for 5 years,
what was the total amount of money earned over the 5 years, to the nearest whole
number?
Answer:776
Step-by-step explanation:
77
Brianna earned a total of approximately $400,652 over the 5 years.
What is an expression?A grouping of variables, symbols, and/or numbers used to represent a mathematical quantity or relationship is known as an expression in mathematics. Expressions might be straightforward with just one number or variable or complex with many terms, operations, and functions.
To find the total amount of money Brianna earned over 5 years, we need to calculate her salary for each of the 5 years and add them up.
In the first year, Brianna's salary was $77,000.
In the second year, her salary increased by 2%, so it became:
$77,000 + 0.02 x $77,000 = $78,540
In the third year, her salary increased by another 2%, so it became:
$78,540 + 0.02 x $78,540 = $80,106.80
In the fourth year, her salary increased by 2% again, so it became:
$80,106.80 + 0.02 x $80,106.80 = $81,700.94
In the fifth and final year, her salary increased by 2% once again, so it became:
$81,700.94 + 0.02 x $81,700.94 = $83,303.11
To find the total amount of money Brianna earned over the 5 years, we just need to add up her salaries from each year:
$77,000 + $78,540 + $80,106.80 + $81,700.94 + $83,303.11 = $400,651.85
Therefore, Brianna earned a total of approximately $400,652 over the 5 years.

Explain for me functions in mathematics
Step-by-step explanation:
You can say that a function take input and outputs something back. for example, let's y = X + 3. You may think this is a equation.Yeah it is but it is also a function. The original function notation is for example f(X) = X+3.But we set y = f(X) so it turn out to be y=X+3.Basically these two have the same meaning.X is a input in the function above.If you set X= 5,the input is now 5 and you will get a kinda output of 5+3 =8.so y= 8 or f(5) = 8.That's all.You can check out more on the internet.

The figure below is a rectangle with the dimensions given. If the perimeter of the rectangle is 48 cm, what are the
dimensions of the rectangle?
Х
3x
Answer:
6 cm and 18 cm.
Step-by-step explanation:
We are given that:
Dimensions of rectangle: x and 3xPerimeter of rectangle: 48 cmThe perimeter of any rectangle is:
L + W + L + WTo determine the dimensions of the rectangle, we need to determine the value of "x". The word "dimensions" are the length and the width of the rectangle. Since the question has not stated the length and width, we can consider the length as x and the width as 3x.
⇒ (x) + (3x) + (x) + (3x)It is also given that the perimeter of the rectangle is 48 cm. Thus, the formula with the length and the width substituted is equivalent to 48 cm.
⇒ (x) + (3x) + (x) + (3x) = 48 cmIt is required for the expression on the left hand side to be simplified. This can be done by combining like terms.
⇒ x(1 + 3 + 1 + 3) = 48 cm⇒ x(8) = 48 cmThen, we can divide 8 both sides to isolate the coefficient from "x". Once the coefficient of "x" is isolated, we will obtain the value of "x".
⇒ x(8)/8 = 48/8⇒ x = 6Finally, substitute the value of "x" into the length and the width. We considered the length to be "x" and the width to be "3x". Therefore,
⇒ Length = x cm = 6 cm⇒ Width = 3x cm = 3(6) cm = 18 cmThus, the dimensions of the rectangle are 6 cm and 18 cm.
Now
2(L+B)=482(x+3x)=482(4x)=488x=48x=6B=6
L=3(6)=18

Which value of b will cause the quadratic equation x2 bx 5 = 0 to have two real number solutions?
A value in the interval (-∞,-2√5] ∪[2√5,∞) will give the two real number solutions.
Given quadratic equation is:
[tex]x^{2} +bx+5=0[/tex]
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0.
To have two real number solutions the discriminant of a quadratic equation should be greater than or equal to zero.
[tex]b^{2} -4(1)(5)\geq 0[/tex]
[tex]b^{2} -20\geq 0[/tex]
[tex]b^{2} -(2\sqrt{5} )^2\geq 0[/tex]
[tex](b+2\sqrt{5} )(b-2\sqrt{5} )\geq 0[/tex]
[tex]b\in(-\infty,-2\sqrt{5} ]\cup [2\sqrt{5} ,\infty)[/tex]
Hence, a value in the interval (-∞,-2√5] ∪[2√5,∞) will give the two real number solutions.

Determine the area of the shaded region. Pool Use 3 for
[tex]\pi[/tex]
Answer:
36 sq in
Step-by-step explanation:
First find the area of the square: 12*12 = 144 in^2
next find the area of 1 circle, im assuming the circles are tangent to the sides of the square and to each other, so each circle has a radius of 12/4 or 3in, the area of each circle is then pi*3^2 or 27 in^2
the total area of the 4 circles is then 27*4 = 108in^2
144-108=36in^2
