Hi there! The answer is A) x = 3 or x = 6

$2 {x}^{2} - 18x + 36 = 0$
Divide by 2.

${x}^{2} - 9x + 18 = 0$
Factor.

$(x - 3)(x - 6) = 0$
Use the rule AB = 0 gives A = 0 or B = 0

$x - 3 = 0 \: \: or \: \: x - 6 = 0 \\ x = 3 \: \: \: \: \: \: \: \: \: or \: \: x = 6$

The answer is A) x = 3 or x = 6

Blababa [14]

Answer:

1,200 +3(60)

Step-by-step explanation:

1200 is where they started so every three hour period the submarine rises 60 ft per hour. So you multiply it by this and then 60. Positive because you are rising, and not going down.
