Answer:
<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Step-by-step explanation:
Given :
Divide throughout by 3 to simplify :
- 1/3 x (3x² - 24x + 12)
- x² - 8x + 4
Using the Quadratic Formula :
- x = -b ± √b² - 4ac / 2a
- x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
- x = 8 ± √64 - 16 / 2
- x = 8 ± √48 / 2
- x = 8 ± 4√3 / 2
- x = 4 ± 2√3
Factors are :
- <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Answer:
135
Step-by-step explanation:

Answer:
7.6^8
Step-by-step explanation:
Answer:
50.24 meters
Step-by-step explanation:
The equation for the circumference of a circle: 2πr
2 x 3.14 x 8 = 50.24
It is D. 320 because if you add 80 and 40 togeter you get 120 then 320
