A) b^2 + 4b + 4
b) x^2 - 9
0.45 because Stock A = 100 and Stock B = 45
Since his stocks inversely decreased you have to do.
Stock A = m cents / share
Stock B = n cents * share
So the equation is
= 100 (0.01m) + 45 (0.01n)
<span>= m + 0.45n</span>
The result of the evaluation of the equation given in the task content is; x =-2.
<h3>What is the solution of the equation?</h3>
It follows from the task content that the equation given whose solution is to be determined is;
3[-x + (2 x +1)]=x-1
The equation can be solved as follows;
-3x + 6x +3 = x-1
2x = -4
x = -2
