Answer:
x=3
Step-by-step explanation:
This can be rewritten as
(x -6)² = 90 . . . . . the left side is already a perfect square
x -6 = ±√90 . . . . . take the square root
x = 6 ±3√10 . . . . add 6
To solve this question, we need to know the triangle inequality property, which states that the sum of two legs of a triangle is always <em>greater </em>(it can't be equal to) than the third leg. Using this property, we can deduct that the only answer that works is A, 6,6, and 5.
F(g(x))=9(-x+3)-2
So: f(g(x)=-9x+27-2=-9x+25
