Awar begins between two countries, causing a need for thousands of new workers to produce uniforms and weapons. what factor that affects the labor market is represented in this situation?

a) social change

b) population shift

c) world event

d) internal government action

I believe the answer is: C. world event

In business, world event refers to the things that occur in the world which influence people to do a certain economic activities as a response. When war occurs, it would create an increase of demand for uniforms and weapons due to the need for product that help soldiers identify enemies/allies along with weapons that help them to survive.

b, the anti immigrant fervor

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
