Question

Do you guys know this.

Answer 1

0.77

Explanation:

You solve the inner first, then move to the outer.

Plug in x = 20 for g(x) =
`(2x+2)/(x-6)`. It should give you
`(42)/(14)`, which simplifies to 3.

You then need to solve f(x) with the given value from g(x), which is 3.

Plug in x = 3 for the equation
`√(0.4x^2-x)`, and you should get
`√(0.6)`.

The answer is roughly 0.77.
