Answer:

x = 19

Step-by-step explanation:

The angles are vertical angles and vertical angles are equal

154 = 6x+40

Subtract 40 from each side

154-40 = 6x+40-40

114= 6x

Divide by 6

114/6 = 6x/6

19 =x

2x^3 + 3x^2 -11x -6 divided by x - 2
Gnesinka [82]

p(x)= x-2

g(x)= 2x^3 + 3x^2 - 11x - 6

first we have to find the zero of the polynomial of x-2

p(x)= x-2 = 0

         x=2

therefore,

p(x)= 2x^3 + 3x^2 - 11x - 6

p(2)= 2*2^3 + 3*2^2 - 11*2 - 6

      = 2*8 + 3*4 - 11*2 - 6

      = 16 + 12 - 22 - 6

      = 28-28

     = 0

Hope it helped u, ^_^.

People in here again and again. I think this is the last question
Lilit [14]

Answer:

2.4 cm

Step-by-step explanation:

We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.

Let's find the midpoint of AB.

  • Segment AB: 10 cm
  • Midpoint of AB: 10/2 = 5 cm

Next let's find the midpoint of BC.

  • Segment BC: 5.2 cm
  • Midpoint of BC: 5.2/2 = 2.6 cm

In order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.

  • 5 cm - 2.6 cm = 2.4 cm

Therefore, the difference between the midpoints of AB and BC is 2.4 cm.
