Answer:
C. 4 feet below
Step-by-step explanation:
A crew member on a boat releases a camera 2 feet above the surface of a lake. That is +2 feet
The camera falls 6 feet. -6
+2+(-6)
2-6
-4
Below 4 feet
For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
