Find the solution(s) to 8x^2 - 56x = 0. check all that apply. a. x= 7 b. x= 0 c. x= -6 d. x= 6 e. x= -7

Answers: X=7, X=0

Step-by-step explanation:

See file attached.

  [A]:  " x = 7 " ;

                [B]:  " x = 0 " ;

Step-by-step explanation:

Given:  " 8x²  -  56x  = 0 " ;

Find the solutions for "x" ;

Divide Each Side of the equation by:  "8" ; to simplify:

   { 8x²  -  56x }  / 8  =  {0 } / 8  ;

to get:

    x²  -  7x  =  0 ;

Now, from the "left-hand side" of the equation:

 we can factor out an "x" :

  x (x  - 7 ) ;

and rewrite the equation:

  x (x  - 7 ) = 0 ;

Note that "any value", multiplied by "zero" , equals "zero");

So, the equation holds true when:

x = 0 ;

and when:

x - 7 = 0 .

When:  " x - 7 = 0 " ;  what does "x" equal?

           Add  " 7 " to both sides of the equation;

              to isolate "x" on one side of the equation; & to solve for "x" ;

            " x - 7 + 7 = 0 + 7 " ;

                  to get:

             " x = 7 ".

So:  The solutions are:  " x = 0 " ;   which is:  Answer choice: {B]:

                              and:  " x = 7 " ;   which is:  Answer choice  [A]:

  The answers are:  [A]:  " x = 7 " ;  and :

                                  [B]:  " x = 0 " .

Hope this helps!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
