8 pm to midnight (12 pm) = 4 hrs
so the temp dropped -16.8 in 4 hrs (because the temp started at 0)
-16.8/4 = -4.2....so it dropped 4.2 every hr.
temp at 9 pm (1 hr after 8) would be (0 - 4.2) = -4.2

Second, -0.75 divided by 2 is -1.5
16:40 as a fraction is 16/40. 16/40 is 4/10 simplified
Answer:
(10x - 5) square units.
Step-by-step explanation:
Let the lengths of equal sides be x units.
Hence, AB + AD + DC = x + x + x = 3x
Therefore, BC = 3x - 2
4z^3 - 6
4*2^3 - 6
4*8-6
32-6
