Answer:

The remaining side has a length of six units.

Step-by-step explanation:

We know that this is an Isosceles triangle because angles A and C are marked as being the same angle. So we know that AB and CB are the same length.

As we're given their lengths, we can simply equate the two, and solve for x:

$x + 4 = 3x - 8\\12 = 2x\\x = 6$

So we know that the remaining side has a length of 6.

This is an exponential growth problem. Exponential growth can be expressed mathematically in the following way:
$y=a (1+r)^{t}$ .
Parameter a presents initial amount.
Parameter r is percentage increase.
Parameter t is time.
An equation that would describe given problem is:
$y=400 (1+0.02)^{t}$
t is the time in years.
