Answer:
The percentage change from 300 to 375 is 25 %
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((375 - 300) / 300) * 100 = 25 %
It would be 40°F, the temperature drops down 2 degrees in one hour, and theres 3 hours til 3:00am, so it dropped 6° then it would 28°F, then it adds 3° every hour until 7:00am, which is 4 hours, so that would be 28°F+12°F= 40°F

Step-by-step explanation:
p²-5p-14=0
p²-7p+2p-14=0
p(p-7)+2(p-7)=0
(p-7)(p+2)=0
either,
p-7=0
p=7
or,
p+2=0
p = -2
hope it helps.
