Answer:
Train got a raise of 16%
Step-by-step explanation:
To find this, start by taking the equation for percent change
(New - Old)/Old * 100 = % Change
Now plug in known values
(580 - 500)/(500) * 100 = % change
80/500 * 100 = % change
.16 * 100 = % change
16 = % change
You just subtract. The standard form of a complex number is a+bi
1 - 4 = -3
-i - (-5i) = 4i
The answer is -3 + 4i
Perimeter of older

Ratio
Ratio of area is also same

- x=7500m²
