Answer:
78 m^2 Unless I got some of the measurements wrong, kinda hard to see them.
Step-by-step explanation:
The surface area will be the sum of the area of each face. so lets see, there is the base (in this orientation) which is a 8x3 rectangle it looks like.
then two trianglular sides with both having a base of 8 and height of 3
then two "roof" pieceswhich are rectangles again, one side of 3 and the other 5.
Now we add each face up.
rectangular base = 3x8 = 24
2 triangular sides = 2(.5*8*3) = 24
2 rectangular roof pieces = 2(5*3) = 30
Now add it all up
24+24+30 = 78
the answer of the question is D

<span>The system of linear equations
−x − y = 1
y = x + 3
can be solved in various ways. This problem hints that you should graph both lines and find the coordinates of their point of intersection.
But we can also solve this system using substitution. Note that y = x + 3. We can subst. x + 3 for y in the 1st equation, as follows:
-x - (x+3) = 1. This simplifies to -x -x - 3 = 1, or -2x = 4, or x = -2.
Since y = x + 3, subbing -2 for x produces y: y = -2 + 3 = 1
Thus, the solution is (-2, 1). </span>
5/6, divide 3/4 to get 0.74 then divide 5/6 to get 0.84 for proof.
