Answer:
not a right triangle
Step-by-step explanation:
These lengths will form a triangle iff ...
10 + 20 > 30 . . . . . false
These side lengths do not form a triangle. It is NOT a right triangle.

<em>Additional comment</em>
We notice the differences between these numbers are the same: 10. The only right triangle with side lengths having the same difference is some multiple of a 3-4-5 right triangle. For a right triangle with side lengths having a difference of 10, the sides would have to be 30, 40, 50--not 10, 20, 30.
I think that it is CD overbar equals XY overbar i think but i really don't know.
Total 52 students.
52 - 17 = 35 students left
35 - 5 = 30 students left
30 - 2 = 28 students left
Each class has 11 students that play ONE sport, which means 22 total in 2 classes. You're on your own now! It's not that hard, I'm sure you'll figure it out.
Hi there! The answer is (1/2)
I suppose you mean the slope of a line that is parallel to y = (1/2)x + 3.
This equation is written in slope-intercept form, which means that the number in front of x represents the slope of the line. The other number represents the y-intercept.
A line that is parallel to another line, will be a line with the same slope. Since the slope of y = (1/2)x + 3 is (1/2), the slope of a line parallel to this line is (1/2) as well.

Answer:
1) -17x-9
Step-by-step explanation:
1)
(-2x^3+x-5)+(x^3-3x-4)
Combine like terms using P.E.M.D.A.S:
(-2x^3+x-5)+(x^3-3x-4)
(-9x-5)+(-8x-4)
Combine like terms:
(-2x^3+x-5)+(x^3-3x-4)
(-9x-5)+(-8x-4)
-17x-9
I hope this helps a bit!☺
