Use the rules of equations and inverse operations to solve the equation. In your final answer, include all of your work. 4 -x^2 = -16

±2√5

Step-by-step explanation:

4 -x^2 = -16  can be rewritten as

20 = x^2.

This quadratic has two solutions:  find them by taking the square root of both sides:

x = ±√20   =  ±√4√5  =  ±2√5

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
