steposvetlana [31]

Answer:

-3t - 33

Step-by-step explanation:

Distribute -3 to all terms within the other parenthesis:

Simplify by multiplying:

(-3)(t) + (-3)(11)

-3t + (-33)

Answer:

Step-by-step explanation:

a) The domain is R- all real numbers.

b) The domain is R- all real numbers.

c) we need

$x^{2}-4\neq 0\\x^{2} \neq 4\\x\neq 2\\and\\x\neq -2$

So the domain is R\{-2, 2}

we need

$x^{2}+x-2\neq 0\\x\neq 1\\and\\x\neq -2$

So the domain is R\{-2, 1}

we need: x-1>0 or x> 1

So the domain is (1,+∞)
