The perimeter of a rectangle is 54 cm. Find its length and width if the length is represented

Anna71 [15]

Answer:

length = 20

width = 7

Step-by-step explanation:

Perimeter of a rectangle is

P = 2(l+w)

54 = 2( 3x+2 + 2x-5)

Combine like terms

54 = 2( 5x -3)

Divide each side by 2

54/2 = 5x-3

27 = 5x-3

Add 3 to each side

27+3 = 5x-3+3

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

3x+2 = 3(6)+2 = 18+2 = 20

2x-5 = 2(6)-2 =12-5 =7

Hotel Management: The Airgle AG800 can purify the air in a conference hall in 20 fewer minutes than it takes the Airgle AG950 to

marta [7]

Let x be the time for the AG800. Then the time for the AG950 is x + 20.
$\frac{1}{x}+\frac{1}{x+20}=\frac{2}{21}$
$\frac{x+20+x}{x(x+20)}=\frac{2}{21}$
Cross-multiplying and simplifying, we get:
$2x^{2}-2x-420=0$
The positive solution to this quadratic is: x = 15.
The answer is: Time for model AG800 = 15 minutes: time for model AG950 = 35 minutes.
