factor completely x^2 − 36.
(x + 6)(x − 6)
(x + 6)(x + 6)
(x − 6)(x − 6)
prime

(x + 6)(x - 6)

Step-by-step explanation:

x² - 36 ← is a difference of squares and factors in general as

• a² - b² = (a + b)(a - b), thus

x² - 36

= x² - 6² = (x + 6)(x - 6)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
