One way of solving this problem can be Heron's formula. It is a formula that allows us to compute the area of a triangle, knowing the length of its three sides.
For the sake of clarity, let's assume that the point in the top-left lies in the origin, and let's call it point A. Then, the "middle" point is point B, and the bottom-right point is point C.
If we fix the coordinate axis with the origin in A, we have the following coordinates for the three points:
We can compute the length of any side using the formula for the distance between two points:
Plugging the approriate values, we get the following lenghts:
Now that we have the lengths, we can use Heron's formula: given the side lenghts 
and the semiperimeter 
, the area is given by
If you plug our values, you will get an area of 6.5. So, unless I'm mistaken, none of the answers seem to mach, whereas 7 seems the best approximation.
Answer:
7.8 rounding up to 8
Step-by-step explanation:
slope = change in y / change is x
slope = rise / run
change in y = -1 (goes down 1)
change is x = 4 (goes right 4)
slope = -1/4
y-intercept, when x = 0
y-intercept = 1 = (0,1)
Expressions can be represented as logarithms and exponents
Rogelio argument is correct
<h3>How to determine if Rogelio's claim is true</h3>
The logarithmic equation is given as:
Apply logarithm rule, to rewrite the logarithmic equation
Evaluate the individual logarithmic expressions
Evaluate the quotient (i.e. divide the expression)
The above equation shows that is between 6 and 7
Hence, Rogelio argument is correct

Answer:
10=x
Step-by-step explanation:
Intersecting Chords Formula:(segment piece) x (segment piece) =
(segment piece) x (segment piece)
6*5 = 3*x
30 = 3x
Divide by 3
30/3 = 3x/3
10 =x
