The Area of rectangle = 80 unit².

<h3>What is Area of rectangle?</h3>

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit into a rectangle. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. You can use the formula of the area of a rectangle to find the space occupied by these objects. For example, let us consider a rectangle of length 4 inches and width 3 inches.

from figure (a)

DE= 40/8 = 5

BC= 100/5 = 20

Now,

AC= AB + BC=  8+ 20 = 28

CE= CD + DE = 10+5= 15

So, area of rectangle

= AC* CE

= 28* 15

= 420

Now, from figure (b)

CD= 24/12= 2

DE= 12/4 = 3

AC= AB+ BC= 14+ 4= 16

CE= CD + DE= 2+3 = 5

So, Area of rectangle= 16*5 = 80 unit²

B) 2(5x - 6) = 3(3x + 1)
Sedaia [141]

Answer:

if you are finding x,

x = 15

Step-by-step explanation:

2(5x-6) = 3(3x+1)

10x - 12 = 9x + 3

10x = 9x + 15

x = 15

The cable supporting a ski lift rises 2 feet for each 5 feet of horizontal length. The top of the cable is fastened 1320 feet ab
ollegr [7]
The resulting triangle is a right triangle with the third side given:
First, the angle can be solved using the given rise and run of the cable. So,
tan θ = 2 / 5
θ = 15.95°

Next, the lengths b and c can be solved using the solved angle:
tan 15.95 = 1320 / b
b = 3300 ft

The hypotenuse or c can be solved by trigonometric functions or using Pythagorean theorem, using the sine function:
sin 15.95 = 1320 / c
c = 4804 ft

Which of the following is the quotient of the rational expressions shown here?
svetoff [14.1K]

For this case we must find the quotient of the following expression:

\frac {\frac {x} {x-1}} {\frac {1} {x + 1}}

Applying double C we have the following expression:

\frac {x (x + 1)} {x-1} =

Applying distributive property to the terms within the parentheses of the numerator we have:

\frac {x ^ 2 + x} {x-1}

Thus, the quotient is given by option A

Answer:

Option A
