Answer:
okay so let's rewrite them
10 × 6 - (2 × 4 -12)
which is = 64
and
2 x 6 - 35 + 4 x 6 -( 3 x 6 - 4)
which is = -13
If the temperature drops 3 degrees ever hour, and she monitors it for 5 hours, then the equation would be 3 x 5 = 15. So the temperature ultimately has dropped 15 degrees during the past 5 hours.
Its D
Because the rate of change is 1.5 and 1.5x10 is 15
