Answer:
Expression: 18 - 12 + 7. In 3 days, the temperature will be 13 degrees.
Step-by-step explanation:
The temperature is 18 degrees.
It will decrease 12 degrees after one day. So, it is 18 - 12.
Then it will increase by 7 degrees after another day. So, it is 18 - 12 + 7.
18 - 12 = 6. 6 + 7 = 13.
So, the expression is 18 - 12 + 7 and the answer is 13 degrees (i think)

Answer:
Sum = 13+ 4i Difference = -5 - 8i
Step-by-step explanation:
Given complex number as (4 -2i) and (9 + 6i)
Sum of these complex number is
(4 -2i) + (9 + 6i) = ( 4 +9) + (6i -2i)
= 13 +4i
Difference of these complex number is
(4 -2i) - (9 + 6i) = (4 -9) - (2i +6i)
= -5 - 8i
Hence the sum and Difference of given complex numbers are
Sum = 13+ 4i Difference = -5 - 8i Answer
