24 x 30 = 720 sq. ft

36 x 108= 3888  sq. inches

3888 inches divided by 12 inches= 324 ft.

720 ft - 324 ft. = 396 ft is the yard only without the garden

Answer:

A₁-A₂=693ft^{2} : Area of the yard, not including the garden

Step-by-step explanation:

Conceptual Analysis

The formula to calculate the area of ​​a surface is:

A=l*w Formula (1)

Where:

A: Area in ft^{2}

l: length in ft

w: width in ft

Nomenclature

A₁: Drake's yard area ,l₁:  Drake's yard length, w₁=  Drake's yard width

A₂: garden area , l₂: garden length, w₂=garden width

Known data

1ft=12 in

l₁=24 ft         w₁= 30 ft

l₂=36 in*1f/12in =3ft        w₂=108 in*1ft/12in=9ft

Problem development

We replace the data in formula (1) to calculate areas:

A₁=l₁* w₁=24 ft *30 ft =720ft^{2}

A₂=l₂* w₂=3 ft *9 ft =27 ft^{2}

A₁-A₂:Area of the yard, not including the garden

A₁-A₂=720ft^{2}-27ft^{2}

A₁-A₂=693ft^{2}

Parallelogram ABCD is given. Draw line EF so that it goes through the vertex A. Point E lies on the side BC and point F lies on
tresset_1 [31]

Answer:

The proof is explained step-wise below :

Step-by-step explanation :

For better understanding of the solution see the attached figure :

Given : ABCD is a Parallelogram ⇒ AB ║ DC and AD ║ BC

Now, F lies on the extension of DC. So, AB ║ DF

To Prove : ΔABE is similar to ΔFCE

Proof :

Now, in ΔABE and ΔFCE

∠ABE = ∠FCE ( alternate angles are equal )

∠AEB = ∠FEC ( Vertically opposite angles )

So, by using AA postulate of similarity of triangles

ΔABE is similar to ΔFCE

Hence Proved.

Solve the polynomial: 2x³-11x²+18x-8=0
kotykmax [81]

Answer:

2/0.74

Step-by-step explanation:

To solve the polynomial, factorize it.

2x³-11x²+18x-8=0

After factorizing:

(x-2)(2x^2 - 7x +4) = 0

now, solve each bracket one by one:

x-2 = 0

x = 2

Then

2x^2 - 7x + 4 = 0

use quadratic formula t get 0.74
