For which of the values of b does the expression 4b - 9 have a value between 90 and 100?

24 or 25

Step-by-step explanation:

if you do 24 x 4 it = 96

if you do 25 x 4 it =100

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
