Answer:

9x² -5

Step-by-step explanation:

(f○g)(x) means f(g(x))

Put the definition of g(x) in place of x in the definition of f(x):

f(g(x)) = f(x²) = 9(x²) - 5

(f○g)(x) = 9x² - 5

Answer:

x=27

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

90 + x+15 + 2x-6 = 180

Combine like terms

3x+99=180

Subtract 99 from each side

3x+99-99=180-99

3x =81

Divide each side by 3

3x/3 = 81/3

x=27
