Answer:
1
Step-by-step explanation:
everything rise 0 power is 1.
For C at 7pm they sold most and at 6 am they sold less
1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side
The answer is 0 because it isn't above 49 and therefore can't be rounded to 100.
Hope this helps :)
