andreev551 [17]
<span>The simple interest formula is:

A = P · (1 + r · t)
where:
A = total amount
P = principal
r = rate
t = time 

Let's solve for r:
A = P + P · r · t
P · r · t = A - P

r = (A - P) / (P · t)

The quantity A - P is defined as the Interest, therefore:
r = I / (P <span>· t)
  = 1020 / (8500 </span>· 4)
  = 0.03

Therefore the rate was 3%.

Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7

The answer will be (-3)^2 for this question, but this is not the full solution.

Hope this helped. Good luck on the rest!
