I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5
1/2(Q+5)
If you only want to know what it means ¨c¨ then it is the Denominator, cause you are referring a fraction.
The area of a Triangle is 1/2BH (B=Base length, H=Height)
When looking at the points, we can figure out the following:
The distance between the two points at the base is 8 (to get from -4 to 4 you must add 8) and the height is 4 (to get from -4 to 0 as well as 0 to 4, the distance is 4).
Now we plug in our values:
Area= 1/2(8)(4)
=1/2(32)
=16 Units squared
Therefore, your answer is 16 units squared.
I hope this Helps!

Since the quantity under a square root must be greater than or equal to zero, you would solve for x by subtracting two, to get that 1/3x must be greater than or equal to zero, then divide by 1/3 on both sides to get that x must be greater than or -6, so the last answer is correct
