Answer:
Length: 9
Width: 2
Step-by-step explanation:
Area = length × width
18 = (x - 5)(x + 2)
18 = x² - 5x + 2x - 10
x² - 3x - 28 = 0
x² - 7x + 4x - 28 = 0
x(x - 7) + 4(x - 7) = 0
(x - 7)(x + 4) = 0
x = 7, -4(not possible)
Length: 7+2 = 9
Width: 7-5 = 2
Painter cost when he use the roller.
40:8=5 hours for painting 40 m²
5+1/2 =5 1/2 where 1/2 is time needed for clean upthe roller
total cost is
(5 1/2)*11=55+11/2=60.5 dollars
Painter cost when he use spray gun
40:20=2 hours for painting 40 m²
2+1=3 time with the time needed for clean up the spray gun
total cost is
3*11+5*3=33+15=48 dollars
60.5-48=12.5 dollars
You save is 12 dollars 50 cents
The data range is: 89 - 12 = 77. So the Range is 77.
