You probably made a typing error in writing s = -3 and wrote s - = 3 instead.

The given expression is:

$-3|15-s|+ 2^{3} \\ \\ 
-3|15-s|+8
$

Substituting the given value of s in the previous equation, we get:

$-3|15-(-3)|+8 \\ \\ 
=-3|15+3|+8 \\ \\ 
=-3|18|+8 \\ \\ 
=-54+8 = -46$

Thus the value of given expression becomes -46 for s = -3

B) BD = DC

Step-by-step explanation:

If AD is a perpendicular bisector of BC with point D on segment BC, then point D is the midpoint of the segment. (That's what "bisector" means.) Each half of the segment is congruent to the other half:

BD = DC
