Answer:
0, -8, 2
Step-by-step explanation:
Opposite of 0 is still 0.
Opposite of 8 = -8
Opposite of the opposite of 2: -2 is the opposite, then the opposite of opposite is -(-2) = 2

Answer:
54
Step-by-step explanation:
To solve this, you have to find the area of the square then the area of the triangle, and add them together.
To find the are of a square you multiply the base by the height.
Example: 6 × 6 = 36
To find the area of a triangle you multiply the base by the height and divide it by 2.
Example: 6 × 6 = 36
36 ÷ 2 = 18
Now we add both areas together.
Example: 36 + 18 = 54
The area of the scale drawing would be 1080 square centimeters or (1080 cm^2). I got this answer through first finding the area of the classroom in feet (which is A= lw = [18][20] = 360 ft^2) and then I proceeded to converting it to centimeters via given scale factor (3 cm = 1 foot) and had the answer of 1080 centimeters squared.
