Answer:
585 miles
Step-by-step explanation:
4x^2-9
(2x+3)(2x-3)
To verify use distributed
2x(2x) +2x(-3)+3(2x)+3(-3)
4x^2-6x+6x-9
4x^2+0-9
4x^2-9
Answer:
n=6

You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.
Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1
10x = 60 Divide by 10
x = 60/10
x = 6
Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10 = Final Result
60 * 1 / 10 = Final Result
Final Result = 6
This method words even when the numbers are quite complicated.
