Answer:
-38
Explanation:
To simplify the expression "6x + 4" when x = -7, we substitute -7 for x and perform the calculation.
Plugging in -7 for x, we have: 6(-7) + 4
Next, we simplify the expression inside the parentheses: -42 + 4
Finally, we combine like terms: -38
Therefore, when x = -7, the value of 6x + 4 is -38.
