D. 360 cm squared
Explanation:
Multiply each faces edges.
18x7(WxL)
3x6(HxW)
3x18(HxL)
multiply each equations answer by 2, because the opposite face is the same.
108x2=216
18x2=36
54x2=108
add these together to get 360 cm squared.

Therefore 
which is a perfect square trinomial
A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. In a perfect square trinomial, two terms will be perfect squares.
Option B) (7x+4)(7x+4) is correct

Answer:
Juan wins the race
Step-by-step explanation:
<em>The complete question is attached.</em>
<em />
Time is on the horizontal axis.
Distance is on the vertical axis.
If you look first at y-axis (vertical), you will see that both lines (curves) go upto a distance of 4 miles. So, the race is of 4 miles. Both of them finish.
Now,
If you look at the corresponding x-axis value of where each curve ends, you will see:
Antonio finishes at 15 mins
Juan finishes at 13 minutes
So we can successfully say that Juan wins the race since he finishes 2 mins faster than Antonio.
Juan wins the race
