Which term best describes any ladder that can be readily moved or carried?

Idon’t see any choices but i think it’s because it’s the work for that class and so the teacher doesn’t get confused

Dis the answer hope this

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing 

Ithink it’s a but it might be wrong so sorry
