Answer:
I got 4e+12 which is d
I think
Step-by-step explanation:
The first question = 3p
The second question =
4x-3y+10z
If it takes a ball to roll 12 meters per sec, and asks how far it will roll for 3 seconds you would multiply 12 and 3 getting 36.
The ball will roll 36 meters for 3 seconds
7x+2x= 54
9x= 54
X=6
Black 7(6)=42
White 2(6)=12
=54
