Answer:
A = [L*T^-3]
B = [L*T^1]
Explanation:
The equation
x = A*t^3 + B*t
has multiple terms that when added together result in x. We know x has dimension of length, so all the terms must have dimensions of length too.
A*t^3 = [L]
A*[T^3] = [L]
A = [L/T^3]
A = [L*T^-3]
And
B*t = [L]
B*[T] = [L]
B = [L/T]
B = [L*T^-1]
