Answer:
The answer is 2
Step-by-step explanation:
2 = 6 + 4n/ 7
cross multiplication
2 x 7 = 6 + 4n
14 = 6 + 4n
4n = 14 -6
4n = 8
n = 8 / 4
n = 2

Answer:
(x + 4)(x + 1)(x + 1) or (x + 4)(x + 1)²
Step-by-step explanation:
Factor both denominators and see what you are missing between them
(x^4)/[(x + 1)(x + 1) -8/[x + 4)(x + 1)]
So in order to get a common denominator, we need
(x + 4)(x + 1)(x + 1) as a denominator, or (x +4)(x + 1)²
