ANSWER :
1.
product of the integers = -168
one number = 14
other integer = -168/14 = -12
check ,
14×-12=-168
2.
temperature at 12 noon = 15° C
temperature decreasing rate = 3°C per hour
temperature at midnight = 15 - ( 3 × 12 )
= 15 - 36 = -21°C
12 hours between noon and midnight .
12×3 = 36
36°C was decreased from temperature at noon .
15 - 36 = -( 36-15 ) = 21
answer = 21°C
hope this answer was correct , good luck .
