- 28 - 40i
note that i² = (√-1)² = - 1
expand product of factors using FOIL
= - 6 - 6i - 14i - 14i² - 20i + 36i²
= - 6 - 6i - 14i + 14 - 20i - 36
= - 28 - 40i

Answer: 240 liters
Step-by-step explanation: This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.
Answer: W= 5000+0.07S
Step-by-step explanation:
Given: A pharmaceutical salesperson receives a monthly salary of $5000 plus a commission of 7% of sales.
Total wages = Monthly salary + 7% of (Monthly sales)
Let salesperson’s monthly wage be W and monthly sales be S.
Then, W = 5000+(0.07) (S) [Convert percent into decimal by dividing it by 100]
Or W= 5000+0.07S
Required linear equation: W= 5000+0.07S
Only cabinet with two silver coins is cabinet B.
The chance of choosing cabinet B is 1/3.
Thus, there is a 1/3 chance of the two cabinets contain 2 silver coins.
