Both numbers have the variable x so you add 5 and 12 which gives you 17 and you need to write the variable. The answer is 17x
Answer:
-6i + 5
Step-by-step explanation:
(3-5i)-(-2+i) = 3 - 5i + 2- i = (-5i - i) + (3 + 2) = -6i + 5
Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. 65°F because we assume that at this temperature we do not need cooling or heating.
In our case the daily mean temperature is 83°F and X is the number of cooling-degree days.
X=83-65
X=18
5=(-4)x-2. Hope this helps
first you need to mulitply 13 x 3 which is 39, then subtract 2 which is 37.
