The perimeter of a certain hexagon is 14.7 centimeters. Five of the sides have the same length of n centimeters, while the one side has a length of 1.9 centimeters, as shown
below.

The value of n is n = 2.56 cm

Option D is correct option.

Step-by-step explanation:

Perimeter of hexagon = 14.7 cm

Five sides have length = n cm

One side has length = 1.9 cm

We need to find value of n

The formula used to find Perimeter of hexagon is :

We can write:

Because 5 sides have length = n so, 5n and one side has length = 1.9

Now, solving to find n

So, The value of n is n = 2.56 cm

Option D is correct option.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
