Question

Select all the expressions that have the same value as 142 – 4b when b = 4.

Answer 1

To determine which expressions are equivalent to 142 − 4b when b = 4, substitute b with 4 and simplify the expression to find that it equals 126. Any expression that simplifies to 126 is equivalent.

Step-by-step explanation:

The student is asking which expressions are equivalent to 142 − 4b when b = 4. To find the equivalent expressions, substitute b with 4 into the original expression. This will result in 142 − 4(4), which simplifies to 142 − 16, and further simplifies to 126.

Any expression that also simplifies to 126 is equivalent to 142 − 4b when b = 4. As part of the problem-solving process, ensure that you perform the operations and simplifications correctly to arrive at the final answer. The problem does not require solving a quadratic equation, but understanding the concept of variable substitution and simplification is key to identifying equivalent expressions.
