1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.
Circumference=pid
d=diameter
circumference=12pi
if you aprox pi=3.141592
c=37.699104 ft

The answer would be -2 you may look at my work to see how I solved it
I'm assuming the given problem is (9+6i) - (1+3i)
If that assumption is true, then this is what the steps look like
(9+6i) - (1+3i)
9+6i - 1-3i
(9-1)+(6i-3i)
(9-1)+(6-3)i
8+3i
<h3>Answer: 8+3i</h3>
