See, please, the suggested explanation:
the equation is y= -|x+3|, where '-' means location of graph in the 3-d quarter, '+3' - the graph is moved to the left on 3 points.
To solve this problem, we need to know the formula of the surface area of a triangular prism. The formula is: A = 2

+ (a+b+c) * h
Now we can substitute values and solve
A = 2(0.5 * 4 * 3) + (3+4+5) * 20
A = 12 + 240
A = 252
That means that the answer to this question is 252 square feet.
The answer would be 1 over 10 (A) because when you multiply two fractions, you multiply the top and bottom so in this case, 1 x 1 is 1 and 2 x 5 is 10 which gives you the answer A.
