First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.
The Statements which are true are;
- Choice B; Subtraction and Addition are INVERSE operations.
- Choice D; Multiplication and Division are INVERSE operations.
Inverse Operations:
Operations said to be inverse if both operations are complementary.
- <em>On this note, when a number x is added to a given number y, we get a number z. Also, when we add x back to the number z; we get number y back.</em>
- <em>Similarly, when we multiply a number, x by y; we get z. When z is then divided by y; we get the number x back.</em>
Ultimately,
- Multiplication and Division are INVERSE operations.
- Addition and Multiplication are INVERSE operations.

To solve this question, use the Cube surface area formula
Area = 6a^2 in which a = edge.
edge = 8.5
Area = 6(8.5)²
Simplify. Follow PEMDAS
Area = 6(72.25)
Area = 433.5
(C) 433.5 in² is your answer
