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.
Answer:
n=4
JK=12
KL=13
Step-by-step explanation:
Since JL=25 and JL=3n+5n-7
Then
3n+5n-7=25 simplifying we get
8n-7=25 subtracting 7 from both sides
8n=32 dividing both sides by 8
n=4
JK?
JK=3n bt n=4
JK=3*4
JK=12
KL?
KL=5n-7
KL=5*4-7
KL=13
