Question

Which expression has a value of -40 when p = 25 and q = 3?

A. 25 - 3 × 5
B. 5 × (25 - 3)
C. 5 - 25 × 3
D. 5 × (25 × 3)

Answer 1

None of the provided expressions (A, B, C, D) evaluate to -40 when substituting p = 25 and q = 3. An error might exist in the options or given values.

Step-by-step explanation:

The question is asking which expression evaluates to -40 when p = 25 and q = 3. Let's evaluate each expression with the given values:

1. A. 25 - 3 × 5: This becomes 25 - 15 which is 10, not -40.
2. B. 5 × (25 - 3): This becomes 5 × 22 which is 110, not -40.
3. C. 5 - 25 × 3: This becomes 5 - 75 which is -70, not -40.
4. D. 5 × (25 × 3): This becomes 5 × 75 which equals 375, not -40.

None of these expressions result in -40 when using the given values for p and q. There might have been an error in the options provided or the values given.

None of the provided expressions, A, B, C, or D, yield a result of -40 when substituting the given values of p = 25 and q = 3. There appears to be a discrepancy between the question and the answer choices, warranting a clarification or correction.
