Step-by-step explanation:
The area of a triangular pyramid is 5 cm.
Answer:
D. –20x + 48
Step-by-step explanation:
–4(5x – 12)
= (-4) (5x) - (-4)(12)
= -20x - (-48)
= -20x + 48
Step-by-step explanation:
present temprature outside=10 degree
temp drops every hour= 5 dgree
let number of hours=h
10 9 8 7 6 5 4 3 2 1 0 hours
--l----l----l----l-----l----l-----l-----l-----l----l----l----l----l-----------
-40-35 -30 -25 -20-15 -10 -5 0 5 10 degrees
it will take 10 hours
for the temperature below -40 degree
h=10
