What best explains why people from nonindustrialized regions constituted the majority of migrants in the nineteenth and early twentieth centuries?

Wow thats alot but it would be the 3 one

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 u should look on google

the correct answer is:

b. substitution property.

if the circle m is with inscribed ∠kjl and congruent radii jm and ml then m = ∠mjl = (kl) because of the substitution property.
