Answer:
-2.5<x<2.5
Step-by-step explanation:
A=8^2
A=64ft^2
A square is defined as a 4 sided shape with all equal sides, so all 4 sides should be 8 feet.
Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft
Speed = distance / time
so ur speed = (3/5) / (3/8) = 3/5 * 8/3 = 8/5 or 1 3/5 miles per hr.
its the first answer choice
10 = Scale factor
The 8 is being raised 10 to get your value on figure (B)
Hope this helps.
Have a great day!
