Answer:
f(5) is NOT 0.
When x=-5, f(x) IS 0.
f(x) divided by (x+5) has a remainder of 0. (x+5) is a factor of f(x).
But x-5 is NOT a factor of x.
Pythagorean theorem a^2+b^2=c^2
First, we subtract 20% of the amount from x, so the initial cost of the furniture should be 80% of x or 0.80x. Then, due to the sales taxs, this amount should be added with 6.25% of itself. Such that,
A = 0.80x + 0.0625(0.80x)
= 0.85x
