I'm going with C. scalene triangle
Answer:
a>4
Step-by-step explanation:
-7a-11<1-4a
ADD 4a to both sides
-3a-11 <1
Add 11 to both sides
-3a <12
Divide both sides by 3
-a <4
Multiply by -1 both sides and FLIP SIGN
a>4
So a should be 5 ,6,7,8.........

[ ] a square bracket when we want to include the number 4
( ) a round bracket when we don't want to include the number 4
