Step-by-step explanation:
Rewriting the formula in standard form would be x^2-8x+14=0
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)
Answer:
tam 20 = 4 / x
x = 4 /tan 20 = 4 / .364 = 10.99
A:
(f+g)(x)=f(x)+g(x)
(f+g)(x)=4x-5+3x+9
(f+g)(x)=7x+4
B:
(f•g)(x)=f(x)•g(x)
(f•g)(x)=(4x-5)(3x+9)
(f•g)(x)=12x^2-15x+36x-45
(f•g)(x)=12x^2+21x-45
C:
(f○g)(x)=f(g(x))
(f○g)(x)=4(3x+9)-5
(f○g)(x)=12x+36-5
(f○g)(x)=12x+31
