Answer:
B. 1,190 square cm
Step-by-step explanation:
For given prism:
l = 16 cm, w = 7 cm, h = 21 cm
Surface area of of the prism

The total distance must be greater than 80. She has already ridden 18 miles. And she will continue to ride m miles per day for at least 6 more days, so:
6m+18>80
More "work"...
distance>80
distance=18+6m
6m+18>80

Both refer to the inverse sine function.
The inverse sine (or arcsine) of x:

where x is a real number in the domain of the function:

and the arcsine function returns an angle in the interval
![\mathsf{\left[-\,\frac{\pi}{2},\,\frac{\pi}{2}\right]:}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Cleft%5B-%5C%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%2C%5C%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%5Cright%5D%3A%7D)

So if you see anywhere one of these expressions below

then you should look for an angle

that satisfies the following conditions:

This angle

is called the inverse sine of the real number x.
______
Pay attention and do not mistake the arcsine function for the reciprocal of sine (which is cosecant); especially if you prefer or see that notation with an superscript -1. This one can be easily mistaken for an exponent:

but the reciprocal is something like
![\mathsf{\big[sin(x)\big]^{-1}=\dfrac{1}{sin\,(x)}=csc(x)\qquad\quad(!!)}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Cbig%5Bsin%28x%29%5Cbig%5D%5E%7B-1%7D%3D%5Cdfrac%7B1%7D%7Bsin%5C%2C%28x%29%7D%3Dcsc%28x%29%5Cqquad%5Cquad%28%21%21%29%7D)
and this last one has a total different meaning.
I hope this helps. =)
Area of the square: 8x7 = 56
Base of triangle: 3+8+3 = 14
Height of triangle: 12-7 = 5
Area of triangle: 1/2(14)(5) = 35
Area of both: 56 + 35 = 91 in.
