Answer:
DE = 80.
Step-by-step explanation:
Since the 2 lines are congruent:
5x = 3x + 32
2x = 32
x = 16
So DE = 3(16) + 32
= 48 + 32
= 80.
Answer: 2x√5
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
I'm not 100% sure but since when you remove the square roots on a and b, you have to add it to X
Answer:
Yes it is a right triangle.
Step-by-step explanation:
Because the Pythagorean Theorem states that 

2. 4(0) - 20(0) < 6
(5/2 (0)) >/= 5(0) - 10 ; it is a solution
3. 2.5 + 5(-1.5) > -10
2.5 - (-1.5) </= 4 ; it is also a solution
x y
( 0 , 0 )
(2.5, -1.5)
Plug it in, plug it in
