GDP is used to measure our country's economic growth but does help in development.

Step-by-step explanation:

From the above question,

Necessary  Condition:

The necessary condition for interference are as follows :

• The light must be monochromatic.
• The distance between screen and slits should be as large as possible.
• There should be narrow sources.

Sufficient condition :

• Particularly for the nation that has federalism, it is important as it allows both the center and the state to function properly and from which one can not regulate the other so it will preserve a partnership between the government and the people.
• Yes One might argue that the Unitary Republic does not require constitutionalism at all. Unlike England, which has an established system, it is the product of a long and systematic phase.

(r+s)(s+t)-(r+s)(s-t)+(r+s)(s+t)

Take (r+s) common, we get

= (r+s)[s+t-(s-t)+s+t]

= (r+s)[s+t-s+t+s+t]

=(r+s)(3t+s)
