Answer:
170.3
Step-by-step explanation:
Round the 2 up because it is followed by a 6
tenths is the first place after the decimal point
Distribute the 6 to each term:
6(a)+6(2b)+6(3c)
Multiply the 6 to each of the terms:
6a+12b+18c
There are no like terms, so 6a+12b+18c is your final answer.
(-19) -7 +14= -26+ 14 = -12
