Answer:

The answer is below

Step-by-step explanation:

The area of the figure = sum of the area of the individual polygons

The area of the figure = x + 1 + y + 1 + x = 2x + y + 2

The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6

The area of the figure = sum of the area of the individual polygons

The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3

The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6

What is the area of the shape?

marshall27 [118]

Step-by-step explanation:

hello,

the shape is a right trapezium.

you use the following formula:

area of a trapezium = ½ × sum of parallel sides× height.

or simply,

a = ½ ( a + b ) h

where a and b are the parallel sides

and h is the height.

thus,

a = ½ × ( 4 + 6 )× 4

a = ½ ( 10 ) × 4

a = 5 × 4

a = 20

have a great day! au revoir !

Ellie, an office manager, needs to find a courier to deliver a package. The first courier she is considering charges a fee of $1

Ber [7]

Answer:

The weight of the package is 1 kilograms.

It will cost $ 13 by both the couriers services.

Step-by-step explanation:

Let the weight of her package is x kilograms

Now, according to the question:

The charges of first Courier = $10 + $3(x)

and The charges of Second Courier = $7 + $6(x)

Also, for x kilograms, both the charges are equal

⇒ $10 + $3(x) = $7 + $6(x)

or, 10 + 3x = 7 + 6x

or, 10 -7 = 6x - 3x

⇒ 3x = 3, implies x = 3/3 = 1

⇒ The weight of the package is 1 kilograms.

It will cost : 10 + 3(1) = $ 13 = 7 + 6(1) by both the couriers services.

Walking path across the park is represented by the equation Y equals negative 2X -7. A new path will be built perpendicular to t

Genrish500 [490]

here the equation of path is -2x-7=y

let us find slope of this line by using y=mx+b

so slope m=-2

now new path is perpendicular to this path.

product of slopes of perpendiculars is -1

so slope of new path is 1/2

now it passes through (-2,-3) with slope 1/2

using y=mx+b to get value of b

-3=1/2(-2) +b

b=-2

plugging m=-1/2 and b=-2 in y=mx + b to get the final equation as

y=(-1/2) x -2 is the equation of new path
