Answer:
-2r^3+4r^2+12r-4
Step-by-step explanation:
6r^3-2r^2+12r-4-8r^3+6r^2
(6r^3-8r^3)+(-2r^2+6r^2)+12r-4
simplify
-2r^3+4r^3+12r-4
2x+3=10^3 now solve for x.....hope it helps
Answer:

Yes.
Step-by-step explanation:
The triangle inequality theorem states that in order for something to be a triangle, any of it's two sides added together must be greater than the remaining side. Because 4 and 5 are the shortest sides and they satisfy the triangle inequality theorem, you can form a triangle.
Answer:
the other 3 sides are 125,55 and 55 - hope this helped :)
Step-by-step explanation:
side 1 = 125
side 2 = 125
side 3 and 4 = ?
360 - 250 = 110
110/2 = 55
side 3 and 4 = 55
