Idk what that answer is soooo
Answer:
B. 4/5
Step-by-step explanation:
So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.
(-3,-2) look at the x axis then the y axis. Remember x comes before y.
Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20
