Answer:

2, 4, 5, and 6 have the same pair of solutions.

Step-by-step explanation:

1. n(n+3)(n-4) = 0

2. 2n(4n+6)(6n-4) = 0

3. 2n(6-4n)(4n-6n) = 0

4. n(2n+3)(3n-2) = 0

5. 2n(2n+3)(3n-2) = 0

6. 3n(6n+9)(9n-6) = 0

Answers:

1. n = 0, -3, 4

2. n = 0, -3/2, 2/3

3. n = 0, 3/2

4. n = 0, -3/2, 2/3

5. n = 0, -3/2, 2/3

6. n = 0, -3/2, 2/3

Answer:

2,4,5,6

Step-by-step explanation:

n=0,4n+6=0\implies n=-\frac{6}{4}=-\frac{3}{2}

6n-4=0\implies n=\frac{4}{6}=\frac{2}{3}

n=0, n=-\frac{3}{2},n=\frac{2}{3}

3.2n(6n-4)(4-6n)=0

n=0

6n-4=0

n=\frac{4}{6}=\frac{2}{3}

4-6n=0

n=\frac{4}{6}=\frac{2}{3}

4.n(2n+3)(3n-2)=0

n=0

2n+3=0

n=-\frac{3}{2}

3n-2=0

n=\frac{2}{3}

5.2n(2n+3)(3n-2)=0

n=0

2n+3=0

n=-\frac{3}{2}

3n-2=0

n=\frac{2}{3}

6.3n(6n+9)(9n-6)=0

n=0

6n+9=0

n=\frac{-9}{6}=-\frac{3}{2}

9n-6=0

n=\frac{6}{9}=\frac{2}{3}

Answer:2,4,5 and 6 equation have same solutions.

A moving company’s moving rates can be represented by the function f(x) = 3x 400, where x is the number of miles for the move. a
goldenfox [79]

The function that represents the difference between the moving companies' rates is:

h(x) = -2x + 200.

<h3>How to find the difference of two functions?</h3>

The difference of two functions is found subtracting the like terms from the functions.

In this problem, the functions for the rates are given as follows:

  • f(x) = 3x + 400.
  • g(x) = 5x + 200

Hence the difference is given by:

h(x) = 3x + 400 - (5x + 200) = 3x - 5x + 400 - 200 = -2x + 200.
