Answer: 12.5%
Step-by-step explanation:
80x 12.5%=10
80+10=90
(-3/8) / (-1/3)
= (<span>-3/8) x (-3)
= 9/8
= 1 1/8</span>
<u>Given</u>:
The given equation is 
We need to determine the exact solutions of the equation.
<u>Exact solution:</u>
The exact solution of the equation can be determined by solving the equation using quadratic formula,

From the equation the values are a = 1, b = -3 and c = -7
Thus, substituting these values in the equation, we get;



Thus, the exact solutions of the given equation is 
Hence, Option A is the correct answer.
Product is multiplication:
x * (x+2) = 201
x^2 +2x = 120
x^2 + 2x -120 = 0
(x+12) (x-10) = 0
x = -12 and x = 10
-12 x -1 = 12
the 2 numbers are 10 and 12
