<h3>
Answer: A) 52 square inches</h3>
==========================================================
Explanation:
a = 8, b = 13, and c = 15 are the sides of the triangle
s = (a+b+c)/2 = (8+13+15)/2 = 18 is the semi-perimeter, aka half the perimeter.
Those values are then plugged into Heron's Formula below

The triangular plaque has an area of approximately 52 square inches.
Okay so the first thing you for for is to see if you can reduce your numbers and you can in this problem. You can reduce the 8 and 12 by 4, meaning that you can divide them by 4. So your problem would now be 2x7/3. Now to calculate your product you just times 2x7 and you’re answer is 14/3 :)
Answer:
Option C is the correct choice that is 
Step-by-step explanation:
As this is a multiple choice question we will reduce the options and work on it with the given points 
Note:We know that
where there is
sign associated with it have a straight line graph there is no breaking in the line.
And when there is simply
we have a dashed line when we plot it on a graph.
So option B and D are discarded.
Now one-by one we will put the values
to know which equation it satisfies.
If we put
then
.
So working with option A.

Plugging the values.

And we know that
must be equal to
so this is not the right answer.
We are left with only one choice that is C .
So option C is the correct option of the above inequality.
