1)a parallelogram is a quadrilateral with opposite sides being parallel so the lines AB must equal CD or otherwise it wouldn't be a parallelogram
2)for a quadrilateral to be proven to be a parallelogram the consecutive angles has to be supplementary which means they add up to 180 or for example you could slice the parallelogram in half down the middle you could piece the two consecutive angles together to make 180 degrees

How can you classify quadrilaterals? Explain using properties of sides and angles.
(Be sure to write at least 5 complete sentences)
Answers
Answer:
A quadrilateral is a polygon with four sides. A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. A rhombus is a parallelogram with four congruent sides. A trapezoid is a quadrilateral with exactly one pair of parallel sides. A kite is a quadrilateral with exactly two pairs of adjacent congruent sides. And A scalene quadrilateral is a four-sided polygon that has no congruent sides. Three examples are shown below.

What is Ray?A ray is a segment of a line where one point is fixed and the other has no defined end. It denotes that a ray has one terminating end and an indefinitely long other end.
The first illustration depicts a ray with an end point at X, which is a phrase that is described as "a ray is a line with one end point."
The second graphic depicts a line segment with endpoints at X and Y. This phrase is described as "A line segment is a line with 2 end points."
The joint of two rays in the third illustration creates an angle, which is once again a defined phrase.
The final illustration depicts a line that is not defined and has no endpoints.

Grandma baked 1.5 times as many pancakes as waffles. After she baked 45 more waffles, and her grandchildren ate 12 pancakes, there were 17 more waffles than pancakes. How many waffles were there initially?
PLS HELP YOU WILL GET BRAINLY!!!
Answers
Step-by-step explanation:
let x represent the no of pancakes,
she baked 1.5 times pancakes more than waffles,
so from this, no of pancakes = 1.5x,
then she baked more 45 waffles,
no of waffles = (x +45)
so you had 1.5x pancakes and the children ate 12 out of them. the no of pancakes has then been reduced by 12.
thus, no of pancakes = ( 1.5x -12 )
now they see that they have 17 more waffles that pancakes left. this means that :
no of waffles - no of pancakes = 17
(x+45) - (1.5x - 12) = 17
x - 1.5x + 45 + 12 = 17
x = -50 / -0.5
x = 100
hence, there were 100 waffles initially.
hope you understand this,

Answers
Expression giving the result of the perimeter of rectangle A and demonstrating the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial
What is the closure property of a polynomial for addition operation?Closure property keeps the result in the same set.
If two polynomials [tex]f(x)[/tex] and [tex]g(x)[/tex] are there.
Then, [tex]f(x) + g(x) = h(x)[/tex]
where [tex]h(x)[/tex] is also a polynomial.
The result of the addition of two polynomials is also a polynomial. This property of polynomial for addition operation is called closure property of a polynomial for addition operation
For the given case, we have:
Length of the rectangle = [tex]3x + 5[/tex]Width of the rectangle = [tex]2x -3[/tex]Perimeter of a rectangle with width W and length L = 2(L + W)
And using that formula, the perimeter of the considered rectangle is evaluated as:
[tex]P = 2(3x + 5 + 2x - 3)\\P = 2((3+2)x + 2) = 2(5x + 2)\\\\P = 10x + 4[/tex]
Thus, expression giving the result of the perimeter of rectangle A and demonstrating the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial

Range of the data set = Maximum value - minimum value = 49 - 40 = 9
Set 3: 85, 98, 31, 96, 49, 77, 82Maximum value = 96, minimum value = 31
Range of the data set = Maximum value - minimum value = 96-31=65
Set 4: 112, 114, 116, 175, 115, 134, 117Maximum value = 175, minimum value = 112

PLEASE HELP ME IF YOU CAN AS SOON AS POSSIBLE. THANK YOU
Answers
(220,10)
Step-by-step explanation:
This reminds me of when I was in middle school
Answer:
(110, 135)
Step-by-step explanation:
From the coordinates given, the shape of the ceiling is a rectangle.
Width = difference in x-coordinates = 220 - 0 = 220
Length = difference in y-coordinates = 260 - 10 = 250
To find the center of the ceiling, we need to find the centroid (center-point) of the rectangle.
x-coordinate = Half of the width + smallest x-coordinate= (220 ÷ 2) + 0 = 110
y-coordinate = Half of the length + smallest y-coordinate = (250 ÷ 2) + 10 = 135
Therefore, the center of the ceiling is at (110, 135)

The number of degrees there are in the angle between the hour and the minute hands of the described clock is; 30°
Angle measure on a wall clockThe conventional analogue wall clock is numbered 1 to 12.
On this note, there are 12 unit subdivisions on the clock.
Each unit subdivision covers angle measure;
360°/12 = 30°Since, at quarter past two; the hour arm of the clock is on 2 and the minute arm is on 3;
It follows that the degree measure of the angle subtended is; 30°.
