Answer: B
<u>Explanation:</u>
rate x time
Chris: 40 x t = 40t
Amy: 60 x t - 2 = 60(t - 2)
Use the distance formula:

Answer: B
<u>Explanation:</u>
x² - 8x + 19
a=1 b=-8 c=19
Use the Quadratic formula to find the solutions for x:






= 4 ± i√3
Solutions are: Factors are:
x = 4 + i√3 x - (4 + i√3) = 0
x = 4 - i√3 x - (4 - i√3) = 0
The answer to this is True
The correct answer should be C. The temperature at which the solid state turns into a liquid state.
A doesn’t make sense (a solid needs to melt, not a liquid)
B is evaporation I would think.
I don’t think that’s possible cause it’s mostly always anonymous
