all of those r correct :)
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if

, the triangle is right
- if

, the triangle is acute
- if

, the triangle is obtuse

The triangle is obtuse.
The answer is D.
Any real numbers , I think
It’s the first one because it subtracts but adds then subtracts
Answer:
250 green marbles
Step-by-step explanation:
We know that there are 25 green marbles in a bag of 40 marbles. Using this, we can say that the probability of pulling a green marble out of the bag is 25/40, or 5/8. To find out how many green marbles Shawna should expect to pull out of the bag after 400 trials, we have to multiply the amount of trials (400) by the probability of pulling out a green marble (5/8).
400 × 5/8 = (400 × 5)/8 = 2000/8 = 250
Shawna should expect 250 green marbles after 400 trials.
I hope you find this helpful. :)
