Answer:
115 3/4
Step-by-step explanation:
Because d=1/2. 1/2*1/2=1/4
C=5 so, C^3=5x5x5
C=125
Next, b=9
Then, you put everything together.
1/4+125-9=125 1/4-9
115 3/4
115 3/4+9 1/4
Answer:
Add 9 to each side of the equation.
Step-by-step explanation:
To complete the square, we need to add (b/2) ^2 to each side, where b is the coefficient of the x terms.
The coefficient of the x terms is -6
so we need to add (-6/2) ^2 = (-3)^2 = 9.
Add 9 to each side of the equation.
Answer: £30.31
Explanation:
100/140 minutes of calls were free. Then, 40 x .09, which is 3.6
