Answer:
144
Step-by-step explanation:
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
- Least Common denominator .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
We have ,
> 1/8 , 2/9 , 3/12 .
The denominator of the fractions are ,
> 8 , 9 , 12
The LCM of 8,9,12 will be ,
2 |<u> </u><u>8</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>1</u><u>2</u><u> </u>
2 <u>| 4 , 9 , 6</u>
2 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>3 </u>
3 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>3 </u><u>,</u><u> </u><u>1</u><u> </u>
Therefore , LCM will be ,
> 2⁴ × 3² = 16 × 9 = 144
Answer:
x = 5 or 1
Step-by-step explanation:
Square both sides to get
x^2 - 6x + 9 = 4 now subtract four from both sides
x^2 -6x+5 = 0 now factor ( or use quadratic formula)
(x-5)(x-1) = 0 so x = 5 or 1
