As we have to solve for b, it means we have to isolate b
So first of all subtract
from both sides
So we get

Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides

Hence option B is correct
Answer:
9x -45
Step-by-step explanation:
The distributive property tells you the factor outside parentheses applies to each of the terms inside parentheses:

= 9x -45
Answer:
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).
Ordering tickets online cost $10 plus additional service charge of $8.
Therefore total cost,C = 10t + 8
Buying tickets at the door cost $12
Therefore, total cost,C = 12t
The system of equation to model the situation are:
C = 10t + 8
C = 12t
