Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Their backyard is rectangular, with a length of 3x – 5 feet and a width of 4x – 10 feet. This means that the area of the backyard is
(3x - 5)(4x - 10)
= 12x² - 30x - 20x + 15
= (12x² - 50x + 15) square feet
Their rectangular swimming pool, along with its surrounding patio, has dimensions of x + 8 by x – 2 feet. This means that the area occupied by the swimming pool and its surrounding patio is
(x + 8)(x - 2)
= x² - 2x + 8x - 16
= x² + 6x - 16
Assuming the swimming pool and its surrounding patio will not be covered with new grass, then the area of the region of the yard that they want to cover with new grass is
12x² - 50x + 15 - (x² + 6x - 16)
= 12x² - 50x + 15 - x² - 6x + 16
= 12x² - x² - 50x - 6x + 15 + 16
= 11x² - 56x + 31 square feet
Line A, because it is the most vertical
Answer:
The maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.
Step-by-step explanation:
Local train stats:
Rate = 60 km/h
Distance = x km
Time = x/60 hours
Express train stats:
Rate = 80 km/h
Distance = 
km
Time = 
hours
Now we will equate both the times.
x = 83.57 km
km
Hence, the maximum distance to the nearest kilometer between Westford and Centerville is 111.43 km.
Answer:
Solution
Correct option is C)
(fog)(x)=f(g(x))=2(3x+2)−1=6x+4−1=6x+3=3(2x+1)
Answer:
x=49750
Step-by-step explanation:
0.1(x + 250) = 5,000
Divide each side by .1
0.1(x + 250)/.1 = 5,000/.1
x+250 =50000
Subtract 250 from each side
x+250-250 = 50000-250
x=49750
