Alternate interior angles theorem
To find surface area, you would find the area of each side of the shape. Since this is a cube, each side is a square. So area=side2, So each side is 9, so 9x9=81 for each face. There are 6 faces to a cube, so 6x81=486 in2 is your answer
Answer:
d
Step-by-step explanation:
1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.
