F(d)=(d+1)(d-1+6)
f(d)=(d+1)(d+5)
f(2)=(2+1)(2+5)
f(2)=(3)(7)
f(2)=21
Answer: divide the numerator(top) by the denominator (bottom) then multiply the answer by 100. Hope this helps!
Answer: Choice C. 
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is
which can be simplified to
or 
In short: x can be -3 or larger.

B. 68
I use the formula A= bh/2 it’s the same thing
8x17 = 136
136/2 = 68
