Answer:
B
Step-by-step explanation:
Because it starts from the smallest negative prefix to largest
Answer:
#3=51. #5=85
Step-by-step explanation:
#3. PEMDAS
(2-10×6)-7
PARENTHESIS FIRST
MULTIPLICATION FIRST
10×6=60
60-2=58
58-7=51
#5. PEMDAS
(12-11)+12×7
PARENTHESIS FIRST
12-11=1
1+12×7
MULTIPLICATION FIRST
12×7=84
84+1=85
Because there are parentheses we distribute the negative signs:
3 - 20i + (-14) - 6i + (-8) + 2i
Next combine like terms:
3 + (-14) + (-8) and -20i - 6i + 2i
-19 -24i
