Answer:
The answer would be C. 40
Step-by-step explanation:
(Kinda hard for me to explain because of symbol)
First, you would use the Sum Rule:
∑a∨n + b∨n = ∑a∨n + ∑b∨n
∑∧4∨i=1 (6i) - ∑∧4∨i=1 (5) <- Leave this one for later
Apply the multiplication rule:
∑c · a∨n = c · ∑a∨n
Then the Sum Formula
= 60
Now, do it to the other part that was left for later!
Do the same process for first part!
1) Sum Rule
2) Multiplication Rule
3) Sum Formula
= 20
Then subtract!
60 -20 = 40
Sorry, if you didn't understand! The sysmbols for me were hard to put and would take up alot of time!
I hope this helped!
