Hey there!

You can use distributive property, as I mentioned in your previous questions.

multiply...
2a² × a = 2a³
2a² × -1 = -2a²
a × a = a²
a × -1 = -a
3 × a = 3a
3 × -1 = -3

add all those terms..
2a³ - 2a² + a² - a + 3a - 3
add the like terms

2a³ - a² + 2a - 3

Hope this helped :)

If f(x) = 9x – 8, which of the following is the inverse of f(x)?

zheka24 [161]

Answer: $f^{-1}$ (x) = $\frac{x+8}{9}$

Step-by-step explanation:

f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes

y = 9x - 8 , then make x , the subject of the formula ,

9x = y + 8

x = $\frac{y+8}{9}$

Finally , replace x , with $f^{-1}$ (x) and y with x , so we have

$f^{-1}$ (x) = $\frac{x+8}{9}$

3 (3n-4)=3 (n+4) help help

tatuchka [14]

(3n-4)=3(n+4)
3n-4=3n+12
no solution

There wouldn’t be a solution to this equation because the n cancels out when you subtract 3n-3n.
