What is the perimeter and area of a polygon?
Answer:
To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

HELLLLLLLLp i dum please help me
Answer:
B
Step-by-step explanation:
(6[tex]x^{5}[/tex]z)^3
6^3 is 226
*(x^2)^3= x^6 (5*3= 15)
*when there are exponents being raised to a power, the exponents are multiplied
**(z^1)^3= z^3 (3*1= 3)
** all numbers are raised to the 1st power (unless otherwise noted x^2, 5^4 2^2, etc)
So the top would end up being 226x^6z^3
Now, since this number is over 4x^4z^2, you need to divide 226x^15z^3 by 4x^4z^2
**divide like terms**
226/4= 54
***x^15/ x^4= x^x^11
*** when you divide exponents, you subtract the bottom number from the top, in this case:
15-4
that equalls 11
So x^11
you do the same for z:
z^3/z^2= z^1 or z (3-2=1 )
You put it all together and you end up with
54x^11z

Answer:
y2 -y1 =4 - y = 2 y has to = 2 because your slope m= - 2/7
x2-x1 =3-10 = -7
Step-by-step explanation:
( 10 , y ) (3 , 4)
x1 y1 x2 y2
We have that for the Question "(10, y) and (3, 4); m= -2/7 find missing value" it can be said that
The value of y is
y=8
From the question we are told
(10, y) and (3, 4); m= -2/7 find missing value
Generally the equation for the slope m is mathematically given as
[tex]m=\frac{y2-y1}{x2-x1}\\\\Therefore\\\\m=\frac{y2-y1}{x2-x1}\\\\-2/7=\frac{4-y}{3-10}\\\\-2/7*-7=4-y\\\\y=4((-2/7)*-7)\\\\[/tex]
y=8
Therefore
The value of y is
y=8

When the table says that there has been a RISE, that means that you should ADD. When the table says there has been a FALL, that means you should SUBTRACT.
The second row and the second column is saying a RISE, meaning that you should ADD 8 and 2. 8 + 2 = 10. So the answer for that one would be 10 degrees celcius (third column, second row.) The numbers in bold are your equation for the second row and fourth column.
Here are the rest: AT MEANS AFTERNOON TEMPERATURE :)
3rd row: AT = -8 [degrees celcius] EQUATION: -2 - 6 = -8
4th row: AT = 3 [degrees celcius] EQUATION: -4 + 7 = 3
5th row: AT = -3 [degrees celcius] EQUATION: 6 - 9 = -3
6th row: AT = -10 [degrees celcius] EQUATION: -5 - 5 = -10
7th row: AT = 0 [degrees celcius] EQUATION: 7 - 7 = 0
Woohoo! We're done with that part now.
(b) So, as I said before, a RISE means you must ADD. If you have a rise in -7 degrees celcius, how would you write that mathematically? You would write it like this: + ( - 7 ). You are ADDING NEGATIVE SEVEN. I know it sounds weird, but it is what it is. NOW. Adding negative 7 IS THE EQUIVALENT of saying subtract seven. Here's an example:
10 + ( - 7 ) = 3 (this is true)
10 - 7 = 3 (this is also true)
Therefore, for b you would say that you agree because +(-7) is the equivalent of say 'minus 7'.

Step-by-step explanation:
JK is formed by J(-12, 3) and K(8,-5). If
line r is the perpendicular bisector of JK, write
an equation for r in slope-intercept form??
Given:
JK is formed by J(-12, 3) and K(8,-5).
Line r is the perpendicular bisector of JK.
To find:
The equation of line r is slope intercept form.
Solution:
Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]
[tex]Midpoint=\left(-2,-1\right)[/tex]
Slope of JK is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]
[tex]m=\dfrac{-8}{20}[/tex]
[tex]m=\dfrac{-2}{5}[/tex]
Product of slopes of two perpendicular lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{2}{5}\times m_2=-1[/tex]
[tex]m_2=\dfrac{5}{2}[/tex]
The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]
[tex]y+1=\dfrac{5}{2}(x+2)[/tex]
[tex]y+1=\dfrac{5}{2}x+5[/tex]
[tex]y=\dfrac{5}{2}x+5-1[/tex]
[tex]y=\dfrac{5}{2}x+4[/tex]
Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].
The required equation of line "r" in slope-intercept form is y = 5/2x + 15
First, we need to find the equation of a line in slope-intercept form as
y = mx + b
m is the slope of the line
b is the y-intercept
Given the coordinate points J(-12, 3) and K(8,-5)
Get the slope of the line
Slope = -5-3/8+12
Slope = -8/20
Slope - -2/5
Slope of the line "r" perpendicular is 5/2
Get the y-intercept of line r
Substitute (8, -5) and m = 5/2 into y = mx + b
-5 = -5/2(8) + b
-5 = -20 + b
b = 15
Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

The additive inverse of -7
Answer:
7
Step-by-step explanation:
An "additive inverse" refers to a number that when added to a specific number equals to "zero."
In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0
Other examples:
1. The additive inverse of 2 is -2 because: 2 + (-2) = 0
2. The additive inverse of -100 is 100 because: -100 + 100 = 0
3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0
The additive inverse of -7 is equal to 7.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.
To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.
So, -7 multiplied by -1 is:
-7 x -1 = 7
Therefore, the additive inverse of -7 is 7.

What is a group of objects that share common characteristics and are well-defined?
Answer:
The options as included in the attachment section are:
A. real numbers B.Cardinality C.element D.Set
The answer is D. Set
Step-by-step explanation:
In mathematics, a set is a group of well-defined objects that share common characteristics as rightly stated in this question. So in a mathematical calculation, the elements or objects collected as a group is called SET. The types of set include empty set, finite set, infinite set, universal set etc.
- Since set represents the whole collection or group, each object, which can be number, letter etc. in the group is an ELEMENT. Likewise, the cardinality of a set refers to the number of elements contained in a particular set.

Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9
