Ok, 6×25=150, since there are 6 sides, the answer is 150cm.
a)
y=4 x +(1.6 X 10)
b)
y=4x +16
c)
x=0 y=0+16 (0,16)
x=1 y=4 +16 (1,20) first day it cost $20
x=2 y=8+16 (2,24) second day it cost $24
x=3 y=12+16 (3, 28) third day it cost $28
plot (0,16) , (1,20), (2,24), (3, 28)
i hope this help
Graph K. This is because the cost of a gallon of milk is not increasing constantly, as in a linear rate, but it has only increased a few times in a year. Therefore, graph K shows that a gallon of milk is a steady, unchanged price, then the cost rises and stays the same, then rises again and stays the same. So, it is not a linear graph because the cost of the milk is not going up at a constant rate.
