Answer:
D) 5
Step-by-step explanation:
Hello!
Let's solve !
⇒ (x - 3)² = 5
⇒ x² - 6x + 9 = 5
⇒ x² - 6x + 4 = 0
⇒ x = -(-6) ± √36 - 4(1)(4) / 2
⇒ x = 6 ± √20 / 2 = 6 ± 2√5 / 2
⇒ x = 3 ± √5
∴ The solutions are x = 3 + √5 and x = 3 - √5.
Associative property of multiplication means that it doesn't matter where the parentheses are placed because it will still be the same answer.
So your answer would be 1, 4 x (3 x 6) = (4 x 3) x 6
I hope this helps!
