get $5,000 back in taxes.
a. What will the fee be for "cash back?"
b. How much will she get back?

10000

step-by-step explanation: divide by 2,

27 +27 or 27times 2=54

the diffrence is 0

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

answer: the actual answer is a. good bank will have the least amount in fees per year.
