Answer:
32 acres
Step-by-step explanation:
The median of an even-length set of numbers is the average of the middle two numbers when they are sorted into order. Here, the numbers are already in order, so the median is the average of the middle two:
(30 acres + 34 acres)/2 = (64 acres)/2 = 32 acres

Answer:
roots : 4, -4, i, -i
Step-by-step explanation:
This gets a bit tricky.
We have to substitude x^2 as u in this problem.
Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get
u^2 - 15u - 16 = 0
( u - 16) (u + 1)
U = 16
U = -1
<em>This is not the end of the problem. </em>
Now we have to substitute x^2 back to u.
x^2 = 16 --> we get the roots 4 and -4
x^2 = -1 --> we get the roots i and -i
tadah!
