The left side can be written as a square. We can take the square root, then subtract 1.
... (x +1)² = 17
... x +1 = ±√17
... x = -1 ±√17

Step-by-step explanation:
It's obvious for an European since it's simple approximation, the cm is just thrown in to confuse Americans.
 
        
                    
             
        
        
        
Isolate the w
w/3 = 5
Note the equal sign. What you do to one side, you do to the other.
Multiply 3 to both sides
w/3(3) = 5(3)
w = 5(3)
Multiply
w = 15
15 is your answer for w

The area of the paper used to wrap the gift is 3 3/4 square feet
<h3>How to determine the total area?</h3>
The dimension is given as:
1 1/4 by 3 
The area is the product of the dimensions.
So, we have
Area = 1 1/4 * 3
Express as an improper fraction
Area = 5/4 * 3
Evaluate
Area = 15/4
Rewrite as:
Area = 3 3/4
Hence, the area of the paper used to wrap the gift is 3 3/4 square feet
