Answer:
Yes, all three of them are proportional
Step-by-step explanation:
First, let's simplify them all the way:
10/45 = 2/9
20/90 = 2/9
6/27 = 2/9
All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.
I assume (x-4)3 means (x-4)³. What we wish is to set the derivative equal to zero.
Expanding the T(x) polynomial makes it easier for me to take the derivative.
So (x-4)³ = x³ - 12x² + 48x - 64 + 6
T'(x) = 3x² - 24x + 48
We can factor out a 3 and set this to zero:
x² - 8x + 16 = 0
(x -4)² = 0
x = 4 should therefore represent the turning point.
I am mildly chagrined, I almost used the f'(x) = nx^(n-1) function at first, which appears would have been correct.
Answer:
This has multiple solutions. For instance a solution could be (3 + 7) + 5 The Commutive Property is just switching up the numbers and put them in a different order/sequence.

(x^2-3x)-(x-3)
x(x-3)-1(x-3)
(x-1)(x-3)
