Answer:
The actual distance is 11.7km
Step-by-step explanation:
2cm = 1km
1cm = 0.5km
23.4cm = ?
23.4 × 0.5 = 11.7km

Answer:
y=(20M+30S) kwh
Step-by-step explanation:
Since each windmill generates M kwh then for ywo windmills, each year they will generate 2 M kilowatt hours
For solar panels, since each generates S kilowatts annually then for 3 of them, the power will be 3 S
Total production per year will be 2M+3S
In n years, the energy will be y(n)=(2M+3S)n
When n is 10 years then
y(10)=(2M+3S)10=20M+30S
Therefore, y=(20M+30S)kwh
Suppose the length is x, the width is then (x-3), the area is x(x-3)
expand it: x²-3x, which is the polynomial you are looking for.
or you can suppose the width is x, the length is then (x+3), the polynomial is x²+3x
