-- A rhombus is always a parallelogram and a quadrilateral.
A rhombus can also be a square, but not all of them are.
-- A rectangle is always a parallelogram and a quadrilateral.
A rectangle can also be a square and a rhombus, but not all of them are.
-- A parallelogram is always a quadrilateral.
A parallelogram can also be a square, a rectangle, or a rhombus, but not all of them are.
-- A quadrilateral can be a square, a parallelogram, a rectangle, and a rhombus.
But not every quadrilateral needs to be any one of these things.

-- You can definitely be sure that every square is always a quadrilateral,
a parallelogram, a rectangle, and a rhombus.
All four choices apply to a square, and should be selected.

Use mental math to solve each equation:
1.). - 52 = - 52 + k
Simplify both sides.
- 52 = - 52 + k
Flip Equation:
k - 52 = - 52
Add 52 both sides:
k - 52 + 52 = -52 + 52
k = 0, Answer: K = 0
3.). x - 155 = 15
Add 155 to both sides:
x - 155 + 155 = 15 + 155
x = 170, Answer: 170
5.). 2,000 + y = 9,500
Simplify both sides:
y + 2000 = 9500
Subtract 2000 from both sides:
y + 2000 - 2000 = 9500 - 2000
y = 7500, Answer: 7500 Graph: 7500
7.). 111 + f = 100
Simplify both sides:
f + 111 = 100
Subtract 111 from both sides:
f + 111 - 111 = 100 - 111
f = - 11, Answer: f = - 11
Solve each equations:
9.). m - 17 = - 8
Add 17 to both sides:
m - 17 + 17 = - 8 + 17
m = 9, Answer: m = 9
11.). - 44 + n = 36
Simplify both sides of the equations:
n - 44 = 36
Add 44 to both sides:
n - 44 + 44 = 36 + 44
n = 80, Answer: n = 80
13.). x - 255 = 671
Add 255 to both sides:
x - 255 + 255 = 671 + 255
x = 926, Answer: x = 926
15.). x + 14 = 21
Subtract 14 from both sides:
x + 14 - 14 = 21 - 14
x = 7, Answer: x = 7
17.). - 19 = k + 9
Flip equation:
K + 9 = - 19
Subtract 9 from both sides:
k + 9 - 9 = - 19 - 9
k = - 28, Answer: k = - 28
19.). 36 + n = 75
Simplify both sides of equation:
n + 36 = 75
Subtract 36 from sides:
n + 36 - 36 = 75 - 36
n = 39, Answer: n = 39
21.). 41 + k = 7
Simplify both sides of equation:
k + 41 = 7
Subtract 41 from both sides:
k + 41 - 41 = 7 - 41
k = - 34, Answer: k = - 34
23.). - 88 + z = 0
Simplify both sides of equation:
z - 88 = 0
Add 88 to both sides:
z - 88 + 88 = 0 + 88
z = 88, Answer: z = 88
Hope that helps!!!! :)
Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.

The data points are a little closer for a weak correlation, and you can see that there is some sort of relationship between these factors.
Data points for a strong correlation are in close proximity to one another, making it possible to build a line by imitating their pattern.
A statistic called correlation gauges how much two variables change in connection to one another.
Correlation and diversification, the idea that certain types of risk can be reduced by investing in assets that are not connected, are closely related concepts.
Correlation cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.
A scatter plot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.
