Answer:

12c - 9d + 3

Step-by-step explanation:

(9 c − 8 d ) + ( 2 c − 6 ) + ( − d + 3 )

Combine like terms ( the d's with the d's, the c's with the c's and the numbers without the variables with the number w.out the variables)

9c - 8d + 3c - 6 - d + 3

12c - 9d + 3

That is at it's simplest form

Hope this helped!

Answer:

$f(g(x))=6x^3} +4$

Step-by-step explanation:

Given:

$f(x)=2x^2+4\\\\g(x)=\sqrt{3x^3}$

Required:

f(g(x))=?

Solution:

let f(g(x))=f(X), where X=g(x)

so $f(X)=2X^2+4$

put X= $g(x)=\sqrt{3x^3}$ , we get

$f(g(x))=2(\sqrt{3x^3} )^2+4$

$f(g(x))=2(\sqrt{3x^3} )^2+4\\\\f(g(x))=2({3x^3} )+4\\\\f(g(x))=6x^3} +4$
