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)
Really big numbers that can easily be estimated.

9,998 - 2,999
Yes you are correct!
So on every triangle there are lines on the inside of each angle
For angle M and A there are 3 lines.
For angle C and P there are 2 lines.
For angle N and B there are 1 line.
If they have the same amount of lines this means that they are congruent.
Soo.. D is correct! :)
