The parallelogram is ABCD with the sides AD parallel to BC

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the figure be represented as ABCD

Now , the sides AD and BC are parallel to each other

And , from the figure , we can say that the sides AB is parallel to CD

Therefore , the figure ABCD is a parallelogram

Step-by-step explanation:

The missing terms of the given arithmetic sequence AP are 14, 21, 28, 35.

An arithmetic progression (AP) is a sequence with the same distinctions between each successive term.

Now, in response to the question;

The arithmetic sequence.14,..., 28, ............

There are total 4 terms in the series.

Let the initial term is  'a₁' is given as 14.

Let the second term is 'a₂'.

Let the third term be 'a₃' which is given as 28.

Ans, the let the fourth term is represented as 'a₄'.

As, we know that in the AP, the difference of the two consecutive terms is equal and called as common difference.

Thus,

d = a₂ - a₁      ........(equation 1)

d = a₃ - a₂     .......(equation 2)

Thus, equating the two equation;

a₂ - a₁ = a₃ - a₂

Substituting the values;

a₂ - 14 = 28 - a₂

Simplifying the equation;

2a₂ = 28 + 14

2a₂ = 42

a₂ = 21.

Put the obtained value in equation 1 and find d.

d = a₂ - a₁

d = 21 - 14

d = 7

Now, estimate a₄.

a₄ = a₃ + d

a₄ = 28 + 7

a₄ = 35

Therefore, the complete arithmetic sequence is 14, 21, 28, 35.

The ratio of quarts of punch to cans of frozen orange is 3/2 with maintaining the ratio to make 4 quarts of a punch we need 2 2/3 cans of frozen orange.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Given that,

2 cans of frozen oranges are used to make 3 quarts of punch.

So,

quarts of punch/cans of frozen oranges = 3/2

Now with the same ratio if we use 4 quarts of punch

Then,

3/2 = 4/ cans of frozen orange

Cans of frozen orange = 4(2/3)

⇒ 8/3 = 2 2/3.

Hence " To make 4 quarts of a punch we need 2 2/3 cans of frozen orange".

The given arithmetic series:

     x+(x+y)+(x+2 y)+ . . . . .

Notice that:

a(1) = x

a(2) = x+y

a(3) = x+2y

We can find the common difference:

d = a(2) - a(1)

Recall the formula for the nth term of an arithmetic series:

a(n) = a(1) + (n - 1) . d

Substitute n = 10, a(1) = x, and d = y into the formula:

a(10) = x + (10 - 1)y

a(10) = x+9y

Use the sum formula:

S(n) = n/2 [a(1) + a(n)]

If the midpoints of a rhombus with 12-inch sides are connected, a quadrilateral is created. A square with a 12-inch diagonal would be the quadrilateral that is constructed.

A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length, a two-dimensional shape, or both. The circumference of a circle or an ellipse is its perimeter. There are numerous practical uses for calculating the perimeter.

Is it possible to find the area of a parallelogram by just multiplying the lengths of two adjacent sides?

It is to find the area of a parallelogram by just multiplying the lengths of two adjacent sides. Let us now find a relation, if any, between the areas of two parallelograms on the same base and between the same parallels.

Answer:

Step-by-step explanation:

False inequality, so no solutions.

y=mx+c, where m is slope. Here x=-2, x-intercept at (x,y)=(-2,0)

and there is no y intercept.

y=mx+c, where m is slope.

The x-intercept is the value of x when y=0.

Since x=-2 for all values of y

it follows that x=-2 when y=0.

The y-intercept is the value of y when x=0 (or alternately the solution point of the form 90,y)). since x neq 0 not matter what value is assigned to y, no such point exists (graphically x=-2 is a vertical line parallel to, and therefore never intersecting, the Y-axis).

Therefore  x-intercept at (x,y) is (-2,0) and there is no y intercept.

The length and the width of the rectangle basee on the perimeter will be 2 and 4cm.

How to calculate the value?

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

b = 2l ------(2)

From equations (1) and (2)

l + 2l = 75

3l = 75

l = 75/3

l = 25 m

Width 'b' = 2(25) = 50 m

Now we have to draw a rectangle with a scale = 25 : 2

Therefore, the scale factor =

l = 2 cm

Similarly,

w = 4 cm

Now we can draw a rectangle with length = 2 cm and width = 4 cm.
