Answer:

Step-by-step explanation:
Let
x -----> Hermione was earning before the pay raise
we know that

so
The linear equation that represent this problem is

Solve for x
Divide by 1.05 both sides



I always start by moving the last term to the other side

To complete the square you take term 'b' , divide it by 2 then square it

= 25
We have to add 25 to what we have and what you do to one side you have to do to the other


Now we factor what is on the left side of the equation

The last step is to move our right side of the equation back over

- which is your answer :)))
Answer:
252
Step-by-step explanation:
Split up the shape
First part:
12*12=144
Second part:
((12+(12-6))/2)*24-12
((12+6)/2)*12
18/2*12
9*12 = 108
Total:
108+144 = 252
