Answer: 9x^2 + 2x - 5
Step-by-step explanation:
6x^2 - 5x + 3 + 3x^2 + 7x -8
Like terms are: (6x^2 and 3x^2), (-5x and 7x), and (3 and -8)
6x^2 + 3x^2 = 9x^2
-5x + 7x = 2x
3 + -8 = -5
9x^2 + 2x - 5 is the simplest answer

Answer:
60°,60° and 60°.
Step-by-step explanation:
The sum of the interior angle of a triangle
=180°
So, let us test measured sets to get which of them could be the interior angles of a triangle.
The sum of the first measured set
= 90° + 42° + 58°
=190°
Also, the sum of the second measured set
= 60°+ 60° + 60°
=180°
The sum of the third measured set,
= 100°+ 48° + 43°
=191°
Finally, the sum of the fourth measured set
= 31° + 75°+ 70°
=176°
We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°
