A. 5

Since both angles are about equal to each other, set them equal to each other in an equation and solve.

2x+4 = 4x-6
-4 -4
2x = 4x-10
-4x -4x
-2x = -10
/ -2 / -2
x = 5

If you want to check, plug 5 in for x on both equations to see if they're the same answers.

2(5)+4 = 14
4(5)-6 = 14

Hope this helped. :)

The length of one of the sides of a regular hexagon is 7.8cm, find the perimeter of this polygon​
fredd [130]

Answer:

46.8 cm

Step-by-step explanation:

A hexagon has six sides. If it is a regular hexagon, then it is equilateral, meaning that each side is the same length. If one side is 7.8cm, then all sides will be 7.8cm. You can find the perimeter by adding 7.8 six times, or multiplying 7.8 by six.

7.8 · 6 = 46.8

hope this helps!

Please answer the circled questions below!
Anton [14]

Answer:

Step-by-step explanation:

1. The y-values in the table are constant, so the slope is 0. It is a horizontal line.

There is no x-intercept.

The y-intercept is (0, 1).

__

For lines in standard form, the intercepts can be found easily. The x-intercept is the value of x when y=0:

  ax +0 = c

  x = c/a . . . . x-intercept

Similarly, the y-intercept is the value of y when x=0:

  0 +by = c

  y = c/b

__

3. x-intercept = (-20/2, 0) = (-10, 0)

  y-intercept = (0, -20/-5) = (0, 4)

__

4. x-intercept = (-6/1, 0) = (-6, 0)

  y-intercept = (0, -6/-3) = (0, 2)

Plot these points and draw a line through them.
