Answer:
26 + 22i
Step-by-step explanation:
Given
(2 + 4i)(7 - 3i) ← expand product using FOIL
= 14 - 6i + 28i - 12i² ← i² = - 1
= 14 + 22i + 12
= 26 + 22i ← in standard form
Answer:
60 miles
Step-by-step explanation:
Let
x ----> the number of miles
we know that
The number of miles multiplied by $0.60 per mile plus $2 plus the charge of $5.50 for tolls (because you are travelling from the airport) must be equal to $43.50
so
The linear equation that represent this problem is
![0.60x+2+5.50=43.50](https://tex.z-dn.net/?f=0.60x%2B2%2B5.50%3D43.50)
Solve for x
Combine like terms left side
![0.60x+7.50=43.50](https://tex.z-dn.net/?f=0.60x%2B7.50%3D43.50)
subtract 7.50 both sides
![0.60x=43.50-7.50](https://tex.z-dn.net/?f=0.60x%3D43.50-7.50)
![0.60x=36](https://tex.z-dn.net/?f=0.60x%3D36)
divide by 0.60 both sides
![x=60\ miles](https://tex.z-dn.net/?f=x%3D60%5C%20miles)
