Answer:

x - 3

Step-by-step explanation:

Given

$\frac{x^2-9}{x+3}$

Note that x² - 9 is a difference of squares and factors as

x² - 9 = (x + 3)(x - 3), thus

$\frac{(x+3)(x-3)}{x+3}$

Cancel the x+ 3 factor on the numerator/ denominator leaving

x - 3 ← in simplified form

To solve this problem, we need to know the formula for the nth term of an arithmetic sequence. The formula is $a_{n}$ = t₁ + (n-1)d, with $a_{n}$ being the nth term, t₁ being the first term, and d being the distance between terms. Now we can substitute values to figure out what $a_{n}$ is. When substituting, the equation becomes:

$a_{n}$ = 12 + 29(-6)
$a_{n}$ = -162

That means that the 30th term in this arithmetic sequence is -162.
