Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))
They are spaced about 0.030 miles apart or 53.33 yards apart. Just divide 1 mile by 33 and get your answer. :) Hope I helped!

Answer
Write an expression for the number of pencils Maggie gives to jamil.
To prove
Let us assume that the number of pencils Katie have = x
As given
Katie gives Maggie half of her pencils.
As given
Maggie keeps 5 and gives the rest to jamil.
Thus
Therefore the expression for the number of pencils Maggie gives to jamil are 
.
It would be: = 56 1/4 % = 225/4% = 225/4/100 = 225/400 = 9/16
In short, Your Answer would be 9/16
Hope this helps!
