Answer:
Below in bold.
Step-by-step explanation:
Find the prime factors:-
126 = 2 * 3 * 3 * 7
234 = 2 * 3 * 3 * 13
So the GCF = 2 * 3 * 3 = 18.
The LCM = 2 * 3 * 3 * 7 * 13
= 1638.
F(x) = ㏑(x² - 4)
Domain: {-2 ≤ x ≤ 2}, or [-2, 2]
17. 2/3
18. 1 1/9
20.9 1/11
21. 2 909/100 (closest i could get)
Hope I helped and hope you had a good day!
Answer:
b = 6
Step-by-step explanation:
Cross multiply: 39(b) = (26)(9)
39b = 234
Divide both sides by 39
b = 6
Answer:
z = -1
Step-by-step explanation:
3(z + 5) = 12
Step 1: Divide both sides by 3.
z + 5 = 4
Step 2: Subtract 5 from both sides.
z = -1
