Step-by-step explanation:
use long division if a calculator is not allowed.
It doesn't matter, both of them are the same.
1/5 = 20/100, or 20%.
A. the first one will give you a perpendicular line to BA
First you have to put like terms together:
bf+af+be+ae
Now you factor the first two terms and then the two last terms:
f(b+a)+e(b+a)
Now you factor even further. By putting what is in parentheses by what is outside the parentheses:
(b+a)(f+e)
What you got is correct as mine is too. I hope this formula helps for future problems:
ax+bx+ac+bc=x(a+b)+c(a+b)
=(a+b)(x+c)
