(x² - 1)^-2/3
∛(x² - 1)-²
∛(1/(x² - 1)(x² - 1))
∛(1/(x^4 - x² - x² + 1))
∛(1/(x^4 - 2x² + 1))
1/x^4/3 - 1.25992105x^2/3 + 1
The average rate of change is (total change in f(x))/(total change in x) so
r=(f(6)-f(2))/(6-2)
r=(36-6-4-4+2+4)/4
r=7
Answer:
mean if 7
Step-by-step explanation:
the mean is 7
Answer:
Step-by-step explanation:
For Perimeter, just times both sides by 2 then add those together:
2(5x+2) + 2(3x+8) = 10x +4 +6x +16 = 16x + 20
If they want a solid #:
16x/16 = -20/16
x = -5/4
16(-5/4) + 20
-20 + 20 = 0
However, I think the first answer would the most likely
For Area, multipy the 2 sides using the box method, foil, etc.
I like using the box method (see image)
For the rest, its basically the same thing. The triangle is just adding the sides together
