Answer: 
Step-by-step explanation:
Atmospheric pressure = 101,325 Newtons / m²
Weight per meter square = 101,325 Newtons
Mass per meter square = 101,325 / (9.81 x 1000)
Mass per meter square = 10.3 tonnes per m²
subtract lowest time from highest time for each kind
129-29 = 100
320-210 = 110
the ranges are about the same but the times are higher for the dark chocolate
30*5=150
32*34=1088
15*19=285
15*3=45
X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6,
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)
