Answer: 2x-5

Step-by-step explanation:

Group like terms. (7x-5x) and (-25+30)

7x-5x is 2x.

The 25 becomes negative due the sign in front of it. -25+30=5.

You cannot solve unlike terms, so your answer is 2x-5.

Another day, another math problem 3

yuradex [85]

Answer:

$2\sqrt{x+1}-3\\domain:[-1, \infty)$

Step-by-step explanation:

$g(h(x)) = 2(\sqrt{x+1})-3\\g(h(x)) = 2\sqrt{x+1} - 3\\$

the function is only defined when (x+1) >= 0 (since square root) so the domain is when x >= -1
