Answer:

Below in bold.

Step-by-step explanation:

The hexagon is made up of 6 equilateral triangles.

So the Base = 12 cm.

Height a = 12 cos 30 = 10.392 cm

So area of 1 triangle = 1/2 * 12 * 10.392 cm^2

- and total area = 6 * 1/2 * 12 * 10.392

= 36 * 10.392

= 374.11 cm^2 to the nearest hundredth.

Answer:

$y = -3+ rx$

Step-by-step explanation:

Given

$Base = -3C$

$Time = x$

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

$y = Base + Rate * Time$

$y = -3+ r* x$

$y = -3+ rx$
