Step 1: -9+n=-18. You would add the inverse to both sides, meaning you’d add nine to the negative nine to cancel it out and then then 9 to -18.
-9+n=-18
+9 +9
That would leave you with the equation: n=-9, since -18 plus a positive 9 equals a negative nine. You’re final answer is n= -9.
You can check you answer by substituting the variable with the solution (-9).
-9 + -9= -18
Answer:

Step-by-step explanation:
The total surface area simply consists of three rectangles and two triangles. To find the total surface of the figure, find the sum of each of the shapes that make up the outside of the figure:
2 triangles: 2 x 1/2 x 6 x 8 = 48 ft^2
First rectangle: 6 x 12 = 72 ft^2
Second rectangle: 8 x 12 = 96 ft^2
Third rectangle: 10 x 12 = 120 ft^2
*Note: One of the dimensions is in yards, so make sure to convert it to ft (1 yd = 3ft)
Thus, the total surface area of the figure is 48+72+96+120 = 336 ft^2.
