Answer:
a < 3
n < 3
Step-by-step explanation:
We will solve each inequality one by one.
Solve first inequality :
3a - 4 < 5
add 4 both the side
3a < 9
divide 3 both the side
a < 3
Solve second inequality:

subtract 5 both the side

now multiply by -3 both the side and reverse the inequality sign
n < (-3)*(-1)
n < 3
That's the final answer. I hope it will help you.
Answer:
5. DBE and CBA both=48 degrees
6. a. scalene, right
b.isosceles, obtuse
c. scalene, acute
7. 50 degrees
8. im not completely sure how to do this one but ill check into it
Step-by-step explanation:
its a lot to explain, in 5 find p and plug it in.
in 6, just look at the sides and angles.
scalene- no sides equal
isosceles- 2 sides equal
equilateral- all sides equal
right- one 90 degree angle
acute- all acute angles (less than 90)
obtuse- one obtuse angle (more than 90)
7. add 90 and 40 to get 130. 180-130=50
8. im gonna look up how to do this one right now

Answer:
6 +8√5
Step-by-step explanation:
The leg length can be reduced to simpler form:
3 +√45 = 3 +√(3²·5) = 3 +3√5
The perimeter is the sum of the side lengths, so is ...
(3 +3√5) +(3 +3√5) +(2√5) = 6 +8√5 . . . perimeter
This is the awnser to the problem
