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.

Answer: 349/192
Hope this helped!
Answer:
17.5 units
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2
Plug in what we know....
9^2+15^2=c^2
81+225=c^2
c=sqrt(306)
c=17.5
