Final answer:
To solve 8+4×2−7, follow the order of operations: perform the multiplication first (4×2=8), add that to 8 (8+8=16), and then subtract 7 to get the final result, which is A) 9.
Step-by-step explanation:
The student is asking for the result of the mathematical expression 8+4×2−7. To evaluate this expression correctly, one must follow the order of operations, commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Following this order:
- Multiplication first: 4×2 = 8.
- Addition next: 8+8 = 16.
- Subtraction last: 16−7 = 9.
Therefore, the correct result of the expression is 9.
