Question

AB=2x+8A, B, equals, 2, x, plus, 8 and
\qquad BC = 6x - 28BC=6x−28

Answer 1

Step-by-step explanation:

Since B is the midpoint,

therefore, AB=BC

=>2x+8=6x-28

=>2x-6x=-28-8

=>-4x=-36

=>x=9

Now,

AC=AB+BC

=2x+8+6x-28

=2×9+8+6×9-28

=18+8+54-28

=52

Answer 2

Answer:

$Given: AB = 2x + 8$

$BC = 6x -28$

To find AC we have to add AB and BC

$AC = AB + BC$

$AC= 2x + 8 + (6x - 28)$

$AC = 2x + 8 + 6x - 28$

$AC= 2 x + 6x + 8 - 28$

$AC= 8x - 20$

Therefore AC = 8x -20
