Answer 2

To evaluate the expression 3x - 7 × |x+5| + 12 at x = -7, we substitute -7 into the expression for x and simplify:

3(-7) - 7 × |-7+5| + 12

= -21 - 7 × |-2| + 12

= -21 - 7 × 2 + 12

= -21 - 14 + 12

= -35 + 12

= -23

Therefore, when x = -7, the value of the expression 3x - 7 × |x+5| + 12 is -23.
