The answer to your question is 2.3
Hope these help:
#9
a-4 divided by 5 = 12
5*12 is 60
60+4 is 64
60 (final answer for a)
#10
n+3 divided by 8 = -4
8*(-4) = -32
-32 + 3 = -35
-32 (final answer for n)
#11
6+z divided by 10 = -2
-2 * 10 = -20
-20=6=-26
-20 (final answer for z)
btw, can't see diagram
Step-by-step explanation:

3. congruent
4. AAS or SAA
I agree only if you have even powers -- even negative ones.
1/i^2 = 1/-1 = - 1
i^0 also gives 1 So far no problem.
It is when you consider the odd numbers that you don't get 1 or -1
You get either -i or i
i^(4n + 1) = i
i^(4n - 1) = -i
