Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:
Final speed of the skateboard(v) = 4 m/s
Answer:
5
Step-by-step explanation:
All you have to do is combine 3x and 5x to = 8x. You can't combine 8x and 67y because they have different variables. so it's 8x+67y.

Adding the powers is 7
so u⁷
