Calculate f(g(x)) and g(f(x)) for each pair of functions.
(note: the notation (fog)(x) and (g (x) mean the same thing, respectively.)
16. f(x) = 3x +7; g(x) = -4x - 11
17. f(x) = - 4x + 60; g
18. f(x) = 10x - 5; g(x
л in
19. f(x) = -x +4; g(x) = -x +6

took the test it's 94

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
