65* It is drawn with a round ruller...
I don't understand this one. explain more and ill be happy to help
<span>You can use Heron's formula to solve this problem.
</span>

, where
A is the area;
a,b,с are the sides;
s<span> is the </span>semiperimeter<span> of the triangle
</span>

<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1
<span>Calculate the semiperimeter:
</span>

<span>Now we can compose and solve the equation according to Heron's formula:
</span>

<span>As a result, x = 6 is your answer.
I hope this helped.</span>

The total order for all the possible combinations is:

The wholesaler requires a minimum of 4 items in each order from its retail customers. This means the retailers can order 4 or more.
Therefore the inequality is:

To graph this inequality, we graph the corresponding linear equation,
with a solid line and shade above.
The correct choice is D
