Answer

Step-by-step explanation:

One solution  :

             x = -1/3 = -0.333

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

               -5*(3*x+1)+4*x-(10*x+2)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((0 -  5 • (3x + 1)) +  4x) -  (10x + 2)  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -21x - 7  =   -7 • (3x + 1)

Equation at the end of step  3  :

 -7 • (3x + 1)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -7   =  0

Choose one of the factors of x^3 + 343.
Debora [2.8K]

First, note that 343=7^3. Then use the formula for the sum of perfect cubes:

a^3+b^3=(a+b)(a^2-ab+b^2).

Therefore,

x^3 + 343=x^3+7^3=(x+7)(x^2-7x+49).

The quadratic trinomial x^2-7x+49 couldn't be factored anymore, so the expression x^3 + 343 has two factors x+7 and x^2-7x+49.

Answer: correct choice is A.
