Answer:
Step-by-step explanation:
a² - b² = (a+ b)(a - b)
1) (2n-4/2n) ÷ (n^2-4/n)
2) [y^2-36/y^2-49] ÷[ y+6/y-7]
3) [m^2-1/ m^2-m] ÷ [m^2-7m-8/3m ]
Hint : m² - 7m - 8
sum = -7
Product = -8
Factor = (-8), 1
m² - 7m - 8 =m² - 8m + m - 8
= m*(m - 8) + (m-8)
= (m - 8)(m +1)
The value of x from the given line segment is 1 2/3.
Given that, line segment AC = 5 and line segment AB = 3x - 5.
We need to find the value of x.
<h3>What is the line segment?</h3>A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.
Since point B is the midpoint of the line segment AC.
AB=BC=3x - 5
Now, AC=AB+BC
⇒5=3x - 5+3x - 5
⇒6x=15
⇒x=15/6
⇒x= 5/3
⇒x=1 2/3
Therefore, the value of x from the given line segment is 1 2/3.
