Answer:
212.5 miles on 25 gallons.
Step-by-step explanation:
Set up a proportion
85 miles on 10 gallons
x miles on 25 gallons.
85/10 = x / 25 Multiply both sides by 25
85*25 / 10 = x Simplify the left
2125 / 10 = x
x = 212.5 miles in 25 gallons.
A^2+b^2=(a+b) (a-b)
Let a^2=x^2 then a^2= x^2
Let b^2=63 them b^2= 64
b=8
Answer: (x+8) (x-8)
