Answer:
the expression that can be used is -12.6 feet - 8.7 feet
Step-by-step explanation:
The computation of the expression that used for determine the Jake new position is as follows;
Given that
Depth of 12.6 feet below the surface
The another 8.7 feet is descended
Based on the above information,
The expression that can be used is
= (-12.6 feet) + (-8.7 feet)
= -12.6 feet - 8.7 feet
hence, the expression that can be used is -12.6 feet - 8.7 feet
