Answer:
54°
Step-by-step explanation:
180° - 52° - 30° = 98°
180 - 98° - 28° = 54°
18² - 4 * 3 * 7 =240
x1 = (-b-root of 240)/2a = ............
x2 =(-b + root of 240)/2a = ........
Answer: 9x²-6x+5
Step-by-step explanation:
To find (gοf)(x), you want to plug f(x) into g(x). It is the same as g(f(x)).
g(f(x))=(3x-1)²+4 [distribute by FOIL]
g(f(x))=9x²-6x+1+4 [combine like terms]
g(f(x))=9x²-6x+5
Now, we know that (gοf)(x)=9x²-6x+5.
