Well if you're solving for x this would be rather simple. 7x +1=68 , then you'd minus 1 from both sides. 7x = 67 then divide 67 by 7. The answer isn't a whole number so x would either be 67/7 or 9.57.. etc.

1)
45x^3+5x
the GCF is 5x because that is a factor of both.
The answer would be 5x(9x^2+1)
2)
u^2-5u+6
factoring is finding what multiplies to the last number to add to the middle number. Those numbers are -3 and -2.
the answer would be (u-3)(u+2)
3)
m^2-49
difference of perfect squares
answer is (m+7)(m-7)
4)
x^5+4x^4+3x^3
GCF is x^3 so it's x^3(x^2+4x+3)
Factor that and it's x^3(x+3)(x+1)
Answer:
hello your question is incomplete below is the missing parts of the question
answer : K = 80
Step-by-step explanation:
P [ x ≤ 1 ] < 0.1
determine how large k have to be
note : n = k
sample proportion = 0.01
E = 0.05 - 0.01 = 0.04
applying this formula below
E = 
0.04 = 1.645 
make n subject of the equation
n = 80.3353
hence the value of K ≈ 80
