Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. 20 / 4*5+9=___
B. the expression is undefined
A. 20 / 4 * 5 + 9 = 100
To simplify the expression 20 / 4 * 5 + 9, we follow the order of operations (also known as PEMDAS), which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
In this expression, we first perform the division: 20 / 4 = 5.
Then, we perform the multiplication: 5 * 5 = 25.
Finally, we perform the addition: 25 + 9 = 34.
So the simplified expression is 20 / 4 * 5 + 9 = 34.
Therefore, the correct choice is:
A. 20 / 4 * 5 + 9 = 34
