  x = ±i/2

Step-by-step explanation:

Factoring, we get ...

  4(4x^2 +1) = 0

  4(2x +i)(2x -i) = 0

The values of x that make the factors zero are ...

  x = -i/2

  x = i/2

The solution is x = ±(1/2)i.

x = i/2

x = -i/2

Explanation:

16x² + 4 = 0

16x² = 0 - 4

16x² = -4

x² = -4/16

x² = -1/4

x = √-1/4

x = 1i/2

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
