F=72
g=6
------------

Therefore:


But what is e?
E=76
G=32
g=6
And:

Which means that:

If you take this value into account, you will discover that f is...

So I would have to say that the answer is approximately (c).
Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A =
(a + b)
Now, substitute the values of the height and the bases:
A =
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100 
Step-by-step explanation:
7 (-12) = -84
it's literally -84
