Answer:
Option 4 is correct.
The equation
is equivalent to 
Step-by-step explanation:'
Given equation: 
First group the terms with x and those with y;

Next, we complete the squares.
We can do this by adding a third term such that the x terms and the y terms are perfect squares.
For this we must either add the same value on the other side of the equation or subtract the same value on the same side so that the equality is maintained.
⇒
or



Add 360 on both sides we get;

Simplify:

Therefore, the given equation is equivalent to 
Answer:

Step-by-step explanation:
Amount deducted for Medicare = $725
Amount deducted for state income tax = $3000
Amount deducted for Social security = $3100
To find: Total amount deducted from Alton's pay for FICA last year

On adding 3725 and 3100, we get 
So, amount deducted = 
Since you said the height of your chair and you desk, chair would go first when subtracting.
C= chair
c - 29.75 = -10.25
+ 29.75 = + 29.75
c= 19.5
So, you chair is 19.5 (19 1/2) inches tall.
