B is the answer, because the half of the balls added
Answer:P=2x + 2y + 8
Step-by-step explanation: Perimeter (p) =2L+ 2w
P= 2(x+5)+2(y-1)
Remove bracket
P=2x+ 10 +2y - 2
P=2x+2y+8
True. The velocity is changing because the direction is changing. Velocity is the combination of speed and direction. The change in velocity leads to a change in acceleration.
