The perfect square
can be expanded as follows:

So, we have to think of the term
as
, which implies
.
Thus, we have to add
, i.e. 16, to complete the perfect square:

Answer:
ANSWER BELOW
Step-by-step explanation:
If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
198 + 36 = 234 sq ft
Have a wonderful day my friend!
4, -4. Additive inverse simply means that the sum = 0, because -4 is the inverse of 4 for the 'sum operation'
