Answer:

yes

Step-by-step explanation:

A difference of squares has the form a² - b² = (a - b)(a + b)

note that 36z² = (6z)² ⇒ a = 6z and 9 = 3² ⇒ b = 3

36z² - 9 is a difference of squares and factors as (6z - 3)(6z + 3)

Answer:

$a_8=38$

Step-by-step explanation:

<u>Recursive sequence </u>

In a recursive sequence formula, each term $a_n$ is computed as a function of one or more previous terms. In the formula

$a_n=a_{n-1}+5$

n is the number of the term we want to calculate. If n=8, then the formula becomes

$a_8=a_{7}+5$

We can see $a_{n-1}$ is the previous term. It means we need $a_7$ to be able to compute $a_8$ . But we also need $a_6$ to compute $a_7$ and so on until some known data is reached. The question provides five terms, $a_5=23.$

$a_6=a_5+5=28$

$a_7=a_6+5=33$

$a_8=a_7+5=38$

$a_8=38$
