Answer:
-2x³ + 16x² + x - 15
Step-by-step explanation:
Multiply the equation in the right bracket with the minus sign
3x3 + 12x2 - 10 - 5x3 + 4x2 + x - 5
Collect like terms
= 3x3 - 5x3 +12x2 + 4x2 + x - 10 - 5
= -2x³ + 16x² + x - 15

Answer:
26°
Step-by-step explanation:
The angle 123° is on a straight line. All angles on a straight line add up to 180°, so the first thing you should do is subtract 123 from 180.
(180-123)
Now, your answer should be 57°, and that is equal to angle W.
You now know two angles. Angles in a triangle add up to 180°, too, so all you do now is the following:
97 + 57 = 154
180- 154 + 26
And there's your answer!
